Toggling these preferences in-game will update your savefile. Meaning that your preferences will persist between rounds.
Added some savefile_version updating stuff. It's pretty crude. If you're changing any of the savefile stuff just ask and I can change it/help.
Removed some unused client vars
Ghosts no longer hear ambience. Simplified ambience code.
Simplified lobby music code. It will no longer cause a massive queue of events (which would eventually balloon in memory use)
Moved ooccolor and sound_adminhelp back to prefs. It's easier and allowed me to remove the setupclient() stuff completely.
