Head of Security Items Update

- HoS jacket can now be buttoned or unbuttoned with a verb.
- The HoS now only gets the jacket and hat he spawns with. I realize this makes the dermal armor patch unobtainable, but I couldn't think of a believable way to toggle the state on that, and the dermal armor patch tends to not communicate well that the person wearing it is armored, so, goodbye for now, armor patch.

(I verified the HoS spawns with a jacket and hat no matter if they latejoined or were HoS from the start of the shift)
