Custom item for YankeeSamurai: Hal Ishimaru
Vox skipjack now filled with nitrogen

Added an oxygen canister, breathmasks and tanks for "guests," thought I
don't think they will be needed since people rarely get to the skipjack
without internals of their own.
Added second vent to skipjack airlocks

Hopefully this will encourage players to not just force the airlock
doors every single time.
Adds a few backpacks to starboard maintenance
Added mechanism to change barsign design, so bartenders aren't stuck with whatever the RNG picks.
Change crew monitoring computer to use NanoUI
Fix NanoUI autoupdating
Change selection interface to have cancel button
Adds some air alarms in mining areas. Includes a few more on station.

Adds an APC to the port aft engineering maintenance, was missing after the addition of drone central.
Adds missing button to close the Xenobiology emergency shutters.
Removes completely unnecessary bits of cable by the virology entrance. Seems to have led to an APC but one already exists in the area.

Mining air alarms with bonus
-Fixed: Trying to build a terminal without enough cables would leave SMES bugged out until VV'ed.
-Made maximum input and output values depend on a variable instead of a define directly. For VV or future customizable SMESes.
-Made reattempting to charge a bit smoother.
-ion_act()'s explosion is now logged.

And that's it. It's just a 30something lines commit, geez.
