Added a username input and team select input that will allow two players
to play on the same computer, this is pretty much what we need for
iteration 1. 


For the inventory we will need to figure out how to switch between these
user names easily.  Im thinking something like a checkIfTurnComplete
type of deal that switches the usernames for us automatically.
new game screen implemented.  

You can now move a single unit south once.  

DO NOT CLICK THE DOWN BUTTON MORE THAN ONCE.
