A Slight nerf to NO2

[Roomba]

I wouldn't mind either nerf to NO2, the stuff can be ridiculous in its current implementation. Mind you, I'm not sure the canister in the armory is that much harder to reach than the one in space - it's pretty easy to tunnel your way in from the back or doorhack your way to it if there's no sec, and quite often you'll have people announcing their intention to packet-hack everything in the armory open and loot it for all it's worth to the general disinterest of the public.
