Workshop Plasma Turrets
Adds a plasma turret to the workshop crafting screen. Crafting it requires both Gun Nut 4 and Science 4, as plasma deals both ballistic and energy damage. Takes 5 power to run, and produces 20 defence. Can be repaired and scrapped, and uses the same barrel model as the playable plasma weapon, meaning that any plasma weapon retextures will also affect the turret.
