rigidbody: Add DNA/RNA/BKE infrastructure for the rigid body sim

Browse Source 
This is just the basic structure, the simulation isn't hooked up yet.

Scenes get a pointer to a rigid body world that holds rigid body objects.
Objects get a pointer to a rigdid body object.

Both rigid body world and objects aren't used directly in the simulation
and only hold information to create the actual physics objects.

Physics objects are created when rigid body objects are validated.
In order to keep blender and bullet objects in sync care has to be taken
to either call appropriate set functions or flag objects for validation.

Part of GSoC 2010 and 2012.
