Add stunguns for heads of staff

[Mordent]

Idea: because the MD has a tranq gun, the HOS and Captain start with energy guns, the hop can give themselves security access, and the RD has literally all of science to kill you with, give the stunguns to the CE only, or at least give the CE something better than a flash to deal with threats.

It's not like it's hard for CEs to make stun gloves.
