Makes the clusterbang launcher unlimited use. Reduces the number of projectiles per reload by half, doubles reload energy cost, and raises the cooldown from 60 to 90. Changes the name to something more humorous from SOP-6 to SOB-3. Raised to mineral cost to that more like the HONK blast.

Only noticeable "bug":the ammo count won't update till the cooldown is over. Also, prevents rearming during the cooldown though.
