Some generic modules from blender 2.4x building with py3k and mostly working.

* 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.
