Nicolás Badano 8d1ee8c2c2 backblast: overhaul
- Replace firedNear by firedBIS XEH
- Calculate the origin of the backblast and overpressure zones using the projectile position and direction
- Handle all effects for each unit on their local machine
- Posibility of drawing effect cone for debug
- Simplified angle calculations
