Fix player controlled range hostiles mobs being unable to fire (#2928)

Pretty much fixes hostiles mobs that had a ranged attack being unable to use it if they are controlled by a player, so, we can have human controlled cavern dwellers and combat drones(in case of adminbus).

Also, fixes a broken design that needed mutagen and being able to transfer reagens to species without blood using an iv.
