Merge branch 'master' of https://github.com/encephalopathy/wepwep
Refactored HomingShotWeapon.lua so it works with our current code base.
Fixed some syntax errors in BulletManager.lua.
Homing Bullets now rotate in the correct direction towards the target.  Not compatible with equipping to Haters yet.
Haters can now use HomingShots if needed.
Fixed a collision detection issue where bullets would pass through haters and not disappear.
