BGE: New Mouse Actuator

Disclaimer: The author of this patch is Geoffrey Gollmer (gomer). I only updated the patch to the current git master status, reworked several parts to fit well with current coding style and applied several fixes.

This actuator allows users to show/hide the mouse cursor using logic bricks, as well as control object rotation with a mouse in the BGE.
The mouse rotation is flexible enough to allow any type of mouse look, as well as banking for flight controls.
