Combat Drones Rework + Fixes

-Combat drones hostile mode now works properly, they can now attack mobs randomly when they malfunction.
-Combat drones additionally had their combat behavior reworked so they maintain a small distance, so that their laser weaponry will actually fire. They had melee behavior before combined with a ranged tag, so that they would run up to an enemy and -never fire-
-Heavily nerfed disabling them because even one ion bolt or being below 30% health for a few ticks would make them nonfunctional almost forever.
-Healing has been slightly buffed, and damage has been slightly nerfed (since they fire 3 shots at once).
-Also, cluwnes no longer attack twice per tick
