[ZNemesis]

I have independantly written an update to this mod which includes Nothing Special.

Compared to the other versions of this mod:
* Being incapacitated now disqualifies you for achievements correctly
* Nothing Special is not disqualified if you are hit while someone else has vomit on them
* Voting to restart the campaign will not reset the achievements (until the new round starts)
* Performance improvements

I have extensively tested my mod.

I don't know if witch damage counts towards disqualification of Nothing Special. I'm going to go with random Gamespot forum poster and say it doesn't, but I've added the code anyway, so its a simple uncomment to enable it.

Thanks to everyone else who worked on this mod, so I didn't have to learn SourceMod from scratch.
