[PR] changes nanomed access to medlocker access

[Froggit_Dogget]

yall are underestimating how fast a mechanic hacks those venders anyway. I think its a good change. If you look at security on main which is whats being argued over here, its almost always stacked with a full secteam, sometimes even a hos and NTSO. Unless a select 5 of us comfertable with handling that many security roll antag, the round is usually very boring, as antags get curbstomped by security. less heals R good.
