Legger til libGdx skjermer og en skjermhåndterer

Legger til en BoardActiveScreen som erstatter GameLauncher sin tidligere funksjon
Legger til en MainMenuScreen som foreløbig bare er en spash screen
Legger til RoboRallyLauncher som fungerer som en forelder til skjermene
Legger til en ScreenManager som kan hente et objekt av hver type skjerm
