Changes in BulletXPlugin: Added new class BulletXActor class inherits from PhysicsActor and it's the ancestor for BulletXCharacter and BulletXPrim.Physical modifications: Changes for pass the value of Physical flag in the SceneObjectPart class to the Physics engines. New call for AddPrimShape so it has a new parameter called "isPhysical". The old call will be obselete soon (i believe). PhysActor and its descendants have a new property called IsPhysical. By the way no new special funcionallity added. It's more like preparing the way for new modifications.
