RoboRumble Rules

Yeah, submit as many as you want, but replace previous versions. If you add DrussGT 2.9.1, remove DrussGT 2.9.0 - you can revert if 2.9.1 is worse. And it's ok to have multiple bots that share some code, even though that's kind of like "different versions".
There's no guideline that it "should be just 1". I have 5, Kawigi has 15, and Stelokim has 20.
