BulletSim: rename some constraint variables to be consistant with other name use.

Added callbacks for shape and body changes in GetBodyAndShape() so the linkset
    constraints can be picked up and restored. A better design might be to have
    a "prim shape changed" event. Think about that.
Added constraint types to general constraint class.
