Cleaned and reviewed FPSCamera
Renamed ViewMover to CameraMover

This better describes its meta function.
Changed how BulletMover works

It now operates on the transform directly. FPSCamera keeps a reference
to it to inform the mover of input, but not the other way around.

This changed required lots of moving of methods to more base classes to
make it a bit more generic.
Some error checking and formatting
Merge remote-tracking branch 'upstream/develop' into develop
removed CameraMover.cpp
