Sig additions

Well, I guess I would like to try and raise the damage of each of my sigs.

Nifelheim would be two hits of 35 instead of 25

Sleipnir would be 11 hits of 10 instead of 9

Fenrir would be two hits of 70 or one hit of 80

I'm not a hundred percent about how the sig powerup works, but is this okay?

DONE, DONE, AND WHAMMO!
