Use software gamma for OSX, fix #134

Browse source 
Hardware gamma is broken, especially in fullscreen, and a Mac user told me
that setting HW/screen gamma on OSX is a bad idea anyway, because it resets
the monitor calibration.
The game /should/ look ok with vid_gamma 1 (if your display is configured
properly), but if you think it's too dark set it a bit higher and do
vid_restart.
