escape key to exit full screen

[Be-ing]

Right click enters fulls screen mode. I expected pressing the escape key to exit full screen mode, but it does nothing. I figured out that right click also exits full screen mode, which is nice to have in addition, but escape is a more conventional way to do that.

ESC isn't bound to anything right now. Since the whole key handling code will require an overhaul, I'll consider adding this shortcut in the process, because you're totally right: it makes sense. Alt-Enter is already there to toggle fullscreen, which is a standard shortcut on Windows for most games.

On a second thought, while still considering to add this as a default, I'll close this issue here in favor of #8 to keep the issue tracker clean, as adding customizable key bindings would serve everyone's personal needs way better than "good" defaults.
