Add muzzle brake accessories

[Taosenai]

ISSUE

By default suppressors in Arma 3 reduce muzzle flash, noise/light signature, and recoil. It would be nice to have muzzle brakes, which would only reduce recoil (by more than a suppressor) while increasing flash/noise signature. These would create interesting choices for players.

PROPOSED SOLUTION

Add muzzle brake attachments for the appropriate weapons: MX, Katiba, Mk200, Zafir.
