remove Spy game mode, add Team Deathmatch game mode

[Heiraphont]

I've had it suggested by players that this be a permanent game mode, and it would never work. For starters, my tribe warfare rounds are TERRIBLY unbalanced. And chaos is really more fun in measured doses, not when it's something that happens every X amount of rounds.

I am glad to see people enjoy it, but I don't think it would be fun after the 50th time in a week.

edit: As a side note? I get as much people saying they hate those rounds as those saying they love it. I think it'd drive far too many people away from the rounds.
