pixel of space in between lines in DrRacket.
This change is based on Matthew's experience having a look
at the font setup on the three platforms.

Before this commit, opening collects/drracket/private/unit.rkt required
about 17.5 megabytes of memory and after this commit, it is down to
about 15 megabytes.
The precise measurement I did was to create a frame and a scheme:text%
object in it, record the result of current-memory-use, open the file,
and record current-memory-use again.
For comparison, using a text:standard-style-list% object instead of
the scheme:text% requires only about 4.1 megabytes. One difference
being that there are about 3x more snips (10,204 vs 33,901 (after the
commit)), since we have one snip for each region that has a different
color in the scheme:text version, and the text:standard-style-list has
no colors and thus about two per line (there are 5006 lines in the
file).
double clicking inside a string) and when clicking on close
parentheses (specifically, only special case close parens that are
actually parentheses according to the colorer, rather than special
casing all close parens).
before the plain text-mode keymap.
Add a doubleleftclick binding to the scheme mode keymap so that
we can have sexp-sensitive double clicking in the drracket editor
and the magic fixup of opening parentheses.
This commit moves the automatic insertion of matching parens to the
scheme mode keymap, so it will now take affect in Racket mode editing,
only. Also, Rackety.
set the keyboard focus to the replace editor.
It used to be disabled when the searching bar is hidden. In that case, it now
makes the searching bar visible.
For example, autocomplete of `cur-dir' will produce the same list of results as the documentation search, with `current-directory' first, instead of producing no results.
line terminators when:
a) running under windows, and
b) the file on the disk (when DrRacket first opens it)
contains all CRLF line endings.
In all other situations, the file is saved with LF terminators.
Before this commit, DrRacket would always use the platform-specific
convention, regardless of the original content of the file.

Instead of generating a file for code and one for documentation, do both
via a macro instead. Most of the code is the same (modulo reformatting
in a more modern style), and instead of printing the result to a file,
it just returns it as the result of a macro. (Since this is done in a
naive way, the macro is bad -- it is unhygienic since this is basically
what it did before only through a generated file; it should eventually
be improved to avoid these hacks.)
specifically add an argument to move/copy-to-edit so that it
does copy-only and export a function for trigger a submission

This is a backwards incompatible change; there is a more complex change
that just stubs this stuff out that may be better that we may need
isntead of this commit.
patterns instead of one pattern per suffix. (This was almost never
used -- only when saving a file that is in text mode.)
* Since this default is the same that the scheme
mode ("framework/private/scheme.rkt") sets, remove that
setting. (Leave it commented in case there's need to have some
different global default.) It makes the above default get used when
saving a scheme-mode file.
* Finally, for some reason the code in "framework/private/finder.rkt"
was not using these `default-filters' at all for the file open dialog
in `*get-file'. (I tracked it back to CVS when the code was written,
and it was never used.)
I made it use it now. This is visible on gtk (and probably on
windows, not sure what OSX does) in that openning a file would show
you all files. After this change, it would show only racket source
files, but there will be an option to switch the pattern to show all files.
** If the previous setup (showing all files) was intentional, it would
be better to simply change "drracket/private/main.rkt" to add the
racket source globs before the default. In that case it might also
make sense to uncomment the change in scheme.rkt back in, so when
saving the default is the racket file suffixes (but this sounds
like a confusing UI).
