Log Message:
-----------
BGE Animations:
* Adding a BL_Action and a BL_ActionManager
* Each KX_GameObject has a BL_ActionManager, which can control up to for
BL_Action objects at a given time
* Currently, the only interface to BL_ActionManager is through KX_GameObject
via Python
* Only armature animations are currently supported
