Create Big Cannons: Going Ballistic

Velocity: All or Nothin'

Changes:

• Fixed a sneaky argument switcheroo that would either produce an underwhelming or overwhelming amount of muzzle velocity for autocannons.
• Fixed a conditional return statement that caused all finite values passed through it to be returned as 0 and all nonfinite values to be clamped, causing some weird behaviours like projectiles not damaging/breaking blocks.
• Fixed a part of the velocity equation that wasn't being calculated correctly that negatively impacted muzzle velocity.
