[PR] changes nanomed access to medlocker access

I like this idea. I see too many officers going and powergaming meds for every ailment under the sun, and in turn be basically unkillable by antagonists. Most rounds the venders get hacked pretty quick if the doctors aren't doing their job anyway, so it won't be too much of an issue if the doctors aren't doing their job. Personally I never play doctor as i feel useless, because most jobs can heal themself before I can get to them as a doctor, and this would be another step in a good direction.
