New Armory Access

[mbc]

the reasoning for it not being relockable was that I wanted it to be an Important Decision that raises the security level of the station for the rest of the round, with no takebacksies. but i'm willing to add relocking if majority opinion favors this

edit : also possible to just let the HoS open the doors anytime and remain unable to relock once the alert level is raised. not sure which solution i prefer though
