Rock Paper Genocide

[Efendija]

I'm not sure how much of this is an actual arrangement of Borderlands 2 music (and how much is original work) so I've added couple of things:

- tr.1 samples the beginning of "The Heavy - Short Change Hero" which was used in B2 intro
- David Eddings's voice clips from the game are in track 4.

Removed B2 composers for now. Maybe somebody will have more accurate info (assuming it's not original work/inspired by songs).
