[PR] changes nanomed access to medlocker access

[AmazingDragons]

Can we not remove things for the purpose of solving a problem that could be handled by ahelps? If people are self-treating on rp that's an issue with them, not with the mechanic. Security officers do need the ability to administer first aid in certain situations, and as a long-time rp player who has both mained doctor and sec, I almost never see this abused. If it is abused, I shoot up an ahelp and it's dealt with. Easy peasy.
