Profiling revealed that the SceneGraph updated every physics object, whether it moved or not, even though the physics object was at the right place. This would cause SOLID to go and update its bounding boxes, overlap tests etc. This callback handles the special case (parented objects) where the physics scene needs to be informed of changes to the scenegraph. Added Python attributes (mass, parent, visible, position, orientation, scaling) to the KX_GameObject module. Make KX_GameObject use the KX_PyMath Python <-> Moto conversion.
