[PR] Headlocking

[cyberTripping]

Sort of a "Desperate times call for desperate measures" type deal, where the Head of a Department can make it easier for people to take action against something.
Maybe the Medical Director can turn off the safety measures for defibs and hyposprays. Sort of like opening the armory.

I think it's important to make sure that any head-locked items aren't just a buff for traitor heads. I feel like the sweet spot for head-locked items would be things that are too risky or dangerous to be made without oversight, but are not easily weaponizable. Something like non-whitelisted hypos would just mean giving the MDir a free new traitor weapon, in my opinion.
