Changed note to todo. Deleted unused vector.
Model: Better naming.
1. Removed onREINITIALIZE from GameObject and fixed #96.
2. Fixed a bug that occurred because PV_Location can not set orientation or position alone.
Look at Physical::onPosition and Physical::onOrientation.
Substituted PV_Location with PV_Position and PV_Orientation.
3. Namestyle fixes and style fixes.
