* Fix for a potential race condition in ScenePresence.AbsolutePosition 

* Unified the way region handles are stored and used in ScenePresence
* Fixed camera position for child agents
* CheckForSignificantMovement now checks avatar and camera position (both are important for scene prioritization)
* Removing debug code from the previous commit
