fixed the separation system. Looks like it was actually in place and working. Now it follows boid flocking behavior. Does some cool stuff with melee now! :D

Seems to work and I tried making it 1.25 tiles, i.e. 40, and the monsters seemed to want to bounce off of each other. When it was 1 tile, i.e. 32, it did not see to cause any bouncing of the monsters. I am assuming we are not bumper cars.
