Fullscreen now available

As some users wished to be able to play Robo Miner in real Fullscreen Mode, this is now possible. To switch to Fullscreen Mode, simply press F11 ingame to toggle between "Fullscreen" and "Windowed Mode" In Fullscreen Mode the game will use your native Screen Resolution. Let me know if you need more control over resolution used in Fullscreen Mode. The game will store your setting, so the next time you start the game it should've remembered your last mode. Hopefully this change is in your favour. Happy Mining!
