[Vala] vapi for the Bullet Physics Engine

[Chris Van Vranken <cessationoftime gmail com>]

I have revised the C-API of the Bullet Physics Engine to be compatible with
the Vala language  (vala-gen-introspect and vapigen) and I have created a
vapi file from it.
I also revised the C-API demo (BulletDinoDemo) that is included in Bullet
and I have recreated it in Vala as a MonoDevelop project.

The modified Bullet-C-API, Vapi file and demos can be found on this page:
http://code.google.com/p/bullet/issues/detail?id=43

If anyone is interested in adding to the Bullet-C-API and vapi file, let me
know as I intend to continue work on it.
