tiny change
cleaned up some camera code and added some functionality for first-person view
increased YAW_MAG (faster turning), redesigned the concept of avatar position, and reset Eve's position accordingly. Also added _frustumNeedsReshape in camera in anticipation of fixing problem where setting fov doesn't reshape the frustum.
added methods to camera class to check for when the view frustum needs to be reshaped (but the calls are not yet being made - need to make sure the right place to use it)
working on camera view shifting from first person to third person
Merge remote-tracking branch 'upstream/master'
