Finally managed to work out some physics. According to my tests, collisions with simple spheres should work with dynamic/kinematic/static objects. There are currently only a limited number of XML parameters, but we're surely going to extend that. Furthermore there is some more thinking to be done concerning changes of btRigidBody properties when it's already added to the world.
