code from Tuesday + fixes

* added stop and flee steering behaviors
* slowed down bullets
* made agents aware of the game
* added finite state machines
* fsm_wander is a place holder, to be filled in by students
* fixed FSM code compared to what was given on Tuesday. (forgot to
divide by 1000 after multiplying by milliseconds!)
