Moved menus to seperate states
PostGame, Main and Highscore menu now seperate states from playState.
Game can now be restarted.
Player can enter name.
Error with input, if listening for a number of keys space+enter, in highscore, and postgame, the statements will automatically be true for some reason.
Merge pull request #16 from frekfra/master
