Remove PK based edge points.

People are multikilling because you get points based on quantity of kills. It's been this way since people found out how that worked.

Given how huge of a gap there is between a character with 1 edge versus a character with 11 edges...min-max people are going to take the path of least resistance to maximize their points (just like people will go revisit every area with scripts to maximize their exploration points).

Honestly, I'd suggest rolling some edges into the classes themselves and make edges actually be less of a factor overall. They're very cool from a mechanical standpoint but they've changed the meta-game too much.
