Adjust random movement actions
Adjust random movement actions

Sometimes, firingsquad bot would not attack when it had a chance, and
would just do random moves. This was because, if the bot was loosing,
the calculated actions would result on boards that were worst (eg:
-3000) than the default random move generator (-1000).

Changed that default value to something really big.
