Adding a battle and matchmaker controller
The battle controller is going to handle the pre-battle stuff... like loading fireteams and things like that.

The match controller will find appropriate matches. Right now all it does is find an ID that doesn't equal the searching fireteam id, but this will later be expanded to find matches that look for more closely related stats (like win/loss ratio and rating).

This commit also has some cleanup to the red_god - I've removed any useless functionality now and it just returns a basic result - no battling takes place. This will occur in another branch.
