An Onslaught gamemode

I've been working on an Onslaught gamemode for someone. I can't particularly remember why I offered to make it, but my memory has always been a bit odd, I'm sure I had a reason.... it features stuff like a reduced-functionality version of the spawnmenu, a class select menu, and lots of stuff trying to kill players. Which is all good, right? Anyway, I really just want an excuse to put more screenshots on my blog. Yay.
