Rats 2.3

- Added a new level system!

There are now 4 levels, Rookie, Semi-pro, Pro, and Master. You level up by winning games, which you can see the progress of on the main menu. Each new level will give you a new badge that will soon be further implemented into the game. In the future, there will be more rewards for each level, but for now it is just the badges and bragging rights.
