[Bf-committers] Bullet physics update

As Dalai Felinto said, I use the 2.49b export patch atm. to get the physics
data out of blender. I do this from makefiles so I've added a GE commandline
param (-g) export_physics = filename; with it the gameengine initializes,
does export and sets exitrequested to "true" before the main-loop.
All in all it's not neat so a bpy-function with similar results would be
nice from a model-exporters perspective, possibly with an
init_bge_pyscript-parameter which would allow advanced users to create
things only available from within the GE. I'm pretty new to bullet and
blender development so I'm not sure what problems this would cause compared
to just having a purely bge based solution.
