add werewolf and wrestler to mixed antag mode

[Sundance]

Yeah wrestler is already a thing, although it's pretty rare.

Would love to see werewolf pop up. Like, we're in dire need of some fresh new modes, and we have werewolves just kinda sitting just there. Only thing is last time I became a werewolf, it was pretty broken. Transforming back to human gave you thw name werewolf and you were a nondescript bald dude.
