* Moved brush NKEY panel from C to Python. Could use some UI review :)
* Added a NULL check in bpy_internal_import.c, was crashing here on Python errors
* Added RNA for vpaint brush and for weight paint
* Added context for vpaint/wpaint similar to edit_object and sculpt_object
* Mathutils, Geometry, BGL, Mostly working, some //XXX comments for things to fix with py3
python import override (bpy_internal_import.c) so you can import python internal scripts from the BGE and running blender normally.
