New 10 man plugin

[ToxicFrank]

This shouldn't affect how often we play on DMF servers, it should just give the community a way to play against each other in a competitive form but still fun. Very few people play just the 10 mans and not the servers but those that do would probably not be in the community as they don't play the other servers. I hope it doesn't affect people as far as playing on the other servers. A number of people are random users who just want to play fun comps against the community. It's pretty laid back and fun.
