Deprecate inheritance modes for position

Deprecate inheritance modes for position

Position will now behave as rotation and scale: either is inherited
from parent or it isn't

If an actor uses one of the following modes for position inheritance:
USE_PARENT_POSITION
USE_PARENT_POSITION_PLUS_LOCAL_POSITION

has to be changed so the actor's anchor point and parent origin is
at the CENTER and in the case of USE_PARENT_POSITION make sure that local
position is (0,0,0)
