Bump version to 2.3.

Before this commit, polylines got flattened but all other entities
got exported with the proper Z coordinate. After this commit, all
entities are exported with proper Z coordinate.

Also, instead of exporting LWPOLYLINE (2d only), POLYLINE (2d/3d)
is exported; as a bonus it is more compatible with 3rd party
software, since it is older.

 Changelog
 =========
 
-3.0
----
-
-New sketch features:
-  * Extrude, lathe, translate and rotate groups can now use the "assembly"
-    boolean operation, to increase performance.
-  * Translate and rotate groups can create n-dimensional arrays using
-    the "difference" and "assembly" boolean operations.
-  * A new sketch in workplane group can be created based on existing workplane.
-  * TTF text request has two additional points on the right side, which allow
-    constraining the width of text.
-  * Image requests can now be created, similar to TTF text requests.
-    This replaces the "style → background image" feature.
-  * Irrelevant points (e.g. arc center point) are not counted when estimating
-    the bounding box used to compute chord tolerance.
-  * When adding a constraint which has a label and is redundant with another
-    constraint, the constraint is added as a reference, avoiding an error.
-  * Datum points can be copied and pasted.
-
-New constraint features:
-  * When dragging an arc or rectangle point, it will be automatically
-    constrained to other points with a click.
-  * When selecting a constraint, the requests it constraints can be selected
-    in the text window.
-  * When selecting an entity, the constraints applied to it can be selected
-    in the text window.
-
-New export/import features:
-  * Three.js: allow configuring projection for exported model, and initially
-    use the current viewport projection.
-  * Wavefront OBJ: a material file is exported alongside the model, containing
-    mesh color information.
-  * DXF/DWG: 3D DXF files are imported as construction entities, in 3d.
-
-New rendering features:
-  * The "Show/hide hidden lines" button is now a tri-state button that allows
-    showing all lines (on top of shaded mesh), stippling occluded lines
-    or not drawing them at all.
-  * The "Show/hide outlines" button is now independent from "Show/hide edges".
-
-New measurement/analysis features:
-  * New command for measuring total length of selected entities,
-    "Analyze → Measure Perimeter".
-  * New command for measuring center of mass, with live updates as the sketch
-    changes, "Analyze → Center of Mass".
-  * When selecting a point and a line, projected distance to to current
-    workplane is displayed.
-
-Other new features:
-  * New command-line interface, for batch exporting and more.
-  * New link to match the on-screen size of the sketch with its actual size,
-    "view → set to full scale".
-  * When zooming to fit, constraints are also considered.
-  * When clicking on an entity that shares a place with other entities,
-    the entity from the current group is selected.
-  * When dragging an entity that shares a place with other entities,
-    the entity from a request is selected. For example, dragging a point on
-    a face of an extrusion coincident with the source sketch plane will
-    drag the point from the source sketch.
-  * In expressions, numbers can contain the digit group separator, "_".
-  * The "=" key is bound to "Zoom In", like "+" key.
-  * The numpad decimal separator key is bound to "." regardless of locale.
-  * On Windows, full-screen mode is implemented.
-
-Bugs fixed:
-  * A point in 3d constrained to any line whose length is free no longer
-    causes the line length to collapse.
-  * Curve-line constraints (in 3d), parallel constraints (in 3d), and
-    same orientation constraints are more robust.
-  * Adding some constraints (vertical, midpoint, etc) twice errors out
-    immediately, instead of later and in a confusing way.
-  * Constraining a newly placed point to a hovered entity does not cause
-    spurious changes in the sketch.
-  * Points highlighted with "Analyze → Show Degrees of Freedom" are drawn
-    on top of all other geometry.

-Contributing to SolveSpace
-==========================
-
-Contributing bug reports
-------------------------
-
-Bug reports are always welcome! When reporting a bug, please include the following:
-
-  * The version of SolveSpace (use Help → About...);
-  * The operating system;
-  * The save file that reproduces the incorrect behavior, or, if trivial or impossible,
-    instructions for reproducing it.
-
-GitHub does not allow attaching `*.slvs` files, but it does allow attaching `*.zip` files,
-so any savefiles should first be archived.
-
-Contributing code
------------------
-
-SolveSpace is written in C++, and currently targets all compilers compliant with C++11.
-This includes GCC 5 and later, Clang 3.3 and later, and Visual Studio 12 (2013) and later.
-
-### High-level conventions
-
-#### Portability
-
-SolveSpace aims to consist of two general parts: a fully portable core, and platform-specific
-UI and support code. Anything outside of `src/platform/` should only use standard C++11,
-and rely on `src/platform/unixutil.cpp` and `src/platform/w32util.cpp` to interact with
-the OS where this cannot be done through the C++11 standard library.
-
-#### Libraries
-
-SolveSpace primarily relies on the C++11 STL. STL has well-known drawbacks, but is also
-widely supported, used, and understood. SolveSpace also includes a fair amount of use of
-bespoke containers List and IdList; these provide STL iterators, and can be used when
-convenient, such as when reusing other code.
-
-One notable departure here is the STL I/O threads. SolveSpace does not use STL I/O threads
-for two reasons: (i) the interface is borderline unusable, and (ii) on Windows it is not
-possible to open files with Unicode paths through STL.
-
-When using external libraries (other than to access platform features), the libraries
-should satisfy the following conditions:
-
-  * Portable, and preferably not interacting with the platform at all;
-  * Can be included as a CMake subproject, to facilitate Windows, Android, etc. builds;
-  * Use a license less restrictive than GPL (BSD/MIT, Apache2, MPL, etc.)
-
-#### String encoding
-
-Internally, SolveSpace exclusively stores and uses UTF-8 for all purposes; any `std::string`
-may be assumed to be encoded in UTF-8. On Windows, UTF-8 strings are converted to and from
-wide strings at the boundary; see [UTF-8 Everywhere][utf8] for details.
-
-[utf8]: http://utf8everywhere.org/
-
-#### String formatting
-
-For string formatting, a wrapper around `sprintf`, `ssprintf`, is used. A notable
-pitfall when using it is trying to pass an `std::string` argument without first converting
-it to a C string with `.c_str()`.
-
-#### Filesystem access
-
-For filesystem access, the C standard library is used. The `ssfopen` and `ssremove`
-wrappers are provided that accept UTF-8 encoded paths.
-
-#### Assertions
-
-To ensure that internal invariants hold, the `ssassert` function is used, e.g.
-`ssassert(!isFoo, "Unexpected foo condition");`. Unlike the standard `assert` function,
-the `ssassert` function is always enabled, even in release builds. It is more valuable
-to discover a bug through a crash than to silently generate incorrect results, and crashes
-do not result in losing more than a few minutes of work thanks to the autosave feature.
-
-### Use of C++ features
-
-The conventions described in this section should be used for all new code, but there is a lot
-of existing code in SolveSpace that does not use them. This is fine; don't touch it if it works,
-but if you need to modify it anyway, might as well modernize it.
-
-#### Exceptions
-
-Exceptions are not used primarily because SolveSpace's testsuite uses measurement
-of branch coverage, important for the critical parts such as the geometric kernel.
-Every function call with exceptions enabled introduces a branch, making branch coverage
-measurement useless.
-
-#### Operator overloading
-
-Operator overloading is not used primarily for historical reasons. Instead, method such
-as `Plus` are used.
-
-#### Member visibility
-
-Member visibility is not used for implementation hiding. Every member field and function
-is `public`.
-
-#### Constructors
-
-Constructors are not used for initialization, chiefly because indicating an error
-in a constructor would require throwing an exception, nor does it use constructors for
-blanket zero-initialization because of the performance impact of doing this for common
-POD classes like `Vector`.
-
-Instances can be zero-initialized using the aggregate-initialization syntax, e.g. `Foo foo = {};`.
-This zero-initializes the POD members and default-initializes the non-POD members, generally
-being an equivalent of `memset(&foo, 0, sizeof(foo));` but compatible with STL containers.
-
-#### Input- and output-arguments
-
-Functions accepting an input argument take it either by-value (`Vector v`) or
-by-const-reference (`const Vector &v`). Generally, passing by-value is safer as the value
-cannot be aliased by something else, but passing by-const-reference is faster, as a copy is
-eliminated. Small values should always be passed by-value, and otherwise functions that do not
-capture pointers into their arguments should take them by-const-reference. Use your judgement.
-
-Functions accepting an output argument always take it by-pointer (`Vector *v`). This makes
-it immediately visible at the call site as it is seen that the address is taken. Arguments
-are never passed by-reference, except when needed for interoperability with STL, etc.
-
-#### Iteration
-
-`foreach`-style iteration is preferred for both STL and `List`/`IdList` containers as it indicates
-intent clearly, as opposed to `for`-style.
-
-#### Const correctness
-
-Functions that do not mutate `this` should be marked as `const`; when iterating a collection
-without mutating any of its elements, `for(const Foo &elem : collection)` is preferred to indicate
-the intent.
-
-### Coding style
-
-Code is formatted by the following rules:
-
-  * Code is indented using 4 spaces, with no trailing spaces, and lines are wrapped
-    at 100 columns;
-  * Braces are placed at the end of the line with the declaration or control flow statement;
-  * Braces are used with every control flow statement, even if there is only one statement
-    in the body;
-  * There is no space after control flow keywords (`if`, `while`, etc.);
-  * Identifiers are formatted in camel case; variables start with a lowercase letter
-    (`exampleVariable`) and functions start with an uppercase letter (`ExampleFunction`).
-
-For example:
-
-```c++
-std::string SolveSpace::Dirname(std::string filename) {
-    int slash = filename.rfind(PATH_SEP);
-    if(slash >= 0) {
-        return filename.substr(0, slash);
-    }
-
-    return "";
-}
-```
-
-Debugging code
---------------
-
-SolveSpace releases are throughly tested but sometimes they contain crash
-bugs anyway. The reason for such crashes can be determined only if the executable
-was built with debug information.
-
-### Debugging a released version
-
-The Linux distributions usually include separate debug information packages.
-On a Debian derivative (e.g. Ubuntu), these can be installed with:
-
-    apt-get install solvespace-dbg
-
-The macOS releases include the debug information, and no further action
-is needed.
-
-The Windows releases include the debug information on the GitHub
-[release downloads page](https://github.com/solvespace/solvespace/releases).
-
-### Debugging a custom build
-
-If you are building SolveSpace yourself on a Unix-like platform,
-configure or re-configure SolveSpace to produce a debug build, and
-then re-build it:
-
-    cd build
-    cmake .. -DCMAKE_BUILD_TYPE=Debug [other cmake args...]
-    make
-
-If you are building SolveSpace yourself using the Visual Studio IDE,
-select Debug from the Solution Configurations list box on the toolbar,
-and build the solution.
-
-### Debugging with gdb
-
-gdb is a debugger that is mostly used on Linux. First, run SolveSpace
-under debugging:
-
-    gdb [path to solvespace executable]
-    (gdb) run
-
-Then, reproduce the crash. After the crash, attach the output in
-the console, as well as output of the following gdb commands to
-a bug report:
-
-    (gdb) backtrace
-    (gdb) info locals
-
-If the crash is not easy to reproduce, please generate a core file,
-which you can use to resume the debugging session later, and provide
-any other information that is requested:
-
-    (gdb) generate-core-file
-
-This will generate a large file called like `core.1234` in the current
-directory; it can be later re-loaded using `gdb --core core.1234`.
-
-### Debugging with lldb
-
-lldb is a debugger that is mostly used on macOS. First, run SolveSpace
-under debugging:
-
-    lldb [path to solvespace executable]
-    (lldb) run
-
-Then, reproduce the crash. After the crash, attach the output in
-the console, as well as output of the following gdb commands to
-a bug report:
-
-    (lldb) backtrace all
-    (lldb) frame variable
-
-If the crash is not easy to reproduce, please generate a core file,
-which you can use to resume the debugging session later, and provide
-any other information that is requested:
-
-    (lldb) process save-core "core"
-
-This will generate a large file called `core` in the current
-directory; it can be later re-loaded using `lldb -c core`.
-
-### Debugging GUI-related bugs on Linux
-
-There are several environment variables available that make crashes
-earlier and errors more informative. Before running SolveSpace, run
-the following commands in your shell:
-
-    export G_DEBUG=fatal_warnings
-    export LIBGL_DEBUG=1
-    export MESA_DEBUG=1
