[Mac] OS X Fullscreen fix.

[Ronald_Reagan]

Heyo all. I just did some updating, and now I want some testing.

If you are a mac user, and you cannot use fullscreen, please give this package a try: http://pbclan.net/downloads/assaultcube_...eenfix.dmg

Note that this is also a development copy of AC, so it has all of the new sexy features stef and grenadier have been working on.

If this works for you, please try doing this as well:
/gamma 120

The expected behavior (bug) is for everything black to go yellow (look at the minimap). If the gamma changes correctly, please tell me. To fix do:
/gamma 100; resetgl

Thanks all!
