A lot of edits and fixes.

 + Fixed bugs random area walker. Now actions stop if the internal
 	representation is different from the real perception. For example
 	the deliberator stop the "planning" if you see a closed door that
 	it thinks it was open.
 + Two new maps.
 + FPSCounter for internal FPS computation.
 + Other hacking for the AIIDE conference. I'm planning to clean all the
 	code from my ugly modification. :P
