A new upload tomorrow. I am too tired.

Fixed all known bugs.
Highscore system works. I only need a highscore table to display ingame and a dialog to enter your name.
Joystick, mouse and keyboard fully supported as input devices (in game and menu).

I will upload a new version when I finished the highscore table (the game already manages highscores and saves them to disk, but only with a preset name ).
