Fun with bullets

* Boosted the max number of bullets to 5000 while testing.
* Bullets fired to the right of the turret head in the correct direction.
  * Need a smart way to deal with shots fired at 0 degrees or 90 degrees
  * Bullets are traveling too quickly if shot near either angle
  * Might be a job for a trig function
* Bullets fired to the left of the turret go in the wrong direction
  * Again, might be a job for a trig function
* Need to prevent shots that would damage bases...or do I?
  * Yeah I probably do
