SystemExitException is instantiated and thrown by Base::Interpreter
whenever the python interpreter executes a sys.exit(<exitCode>) call.
However, in the current implementation, the SystemExitException
effectively swallows the <exitCode> hence under this change,
SystemExitException has been extended to save the <exitCode> passed to
the sys.exit() call when it is instantiated and provides a new
getExitCode() accessor method to retrieve the <exitCode> in a
try/catch block. MainGui.cpp was change to pass the corresponding
<exitCode> to the system exit() call so it is accessible in the shell.
We did not have document icons defined for OS X and the existing legacy
icons were low resolution. For this change, we have created a
freecad-doc.svg icon that serves as the basis for generating
platform-specific FreeCAD document icon sets for the supported
platforms. Extended the OS X bundle definition to include the
high-resolution document icon set and regenerated the existing 64x64
Gui/Icon/freecad-doc.png from the new svg variant.

1. Enhanced TestApp.py to return the unittest TestResult object to the calling method
2. FreeCADTest.py now checks the TestResult object. If all tests pass, FreeCADTest.py exits with a 0 however if any tests fail, then it exits with 1. FreeCADTest.py calls os._exit() with the exit code instead of sys.exit() because Base::Interpreter:SystemExitException intercepts sys.exit() calls and swallows the exit code so there is no way to propogate the non-zero code from the python test cases through the interpreter to the shell in the current call stack.
