BGE patch: logic optimization part 2: remove inactive sensors from logic manager.

Browse Source 
With this patch, only sensors that are connected to 
active states are actually registered in the logic
manager. Inactive sensors won't take any CPU,
especially the Radar and Near sensors that use a
physical object for the detection: these objects
are removed from the physics engine.

To take advantage of this optimization patch, you
need to define very light idle state when the 
objects are inactive: make them transparent, suspend
the physics, keep few sensors active (e,g a message
sensor to wake up), etc.
