Remove friendly-fire self damage

[Freddy_Krueger_of_MandB]

I'm not sure if this is possible, but I feel like the damage you receive when hitting a teammate is anti-teamwork, and can lead to some frustration if you are playing as a high level with lower level characters. With my pikeman, if I headshot a redshirt I lose pretty much all of my health. The reason that this can be frustrating is that many low level characters don't know that this can happen and run in front of attacks. I'm not sure if there is a reason for the self damage to be in the game, but if it is possible to remove I think that it would benefit the game overall.
