Clan war requirements

[hotshot64]

Right now warring members can bring in "mercenaries" when forcing on someone. I propose you change that requirement to be somewhat like pking; have consequences if you force on an enemy while grouped with someone who isn't part of your alignment. Otherwise it's just a way of settling vendettas without risk to yourself by grouping with an aligned person, or a way of killing enemies by virtue of non-aligned players assisting you.
