Arc Smelter area suggestions

[Silvercloud29]

I know restricting access to the smelter later in development was the original plan, but plans change; people are quite accustomed to it being public access now, and it's lead to all sorts of amazing shenanigans. Maybe the public access could use some prettying up, but I think it should still be available to everyone without the need for hacking.

This is like saying we should have chem dispensers out in the halls instead of science since everyone likes making hellmixes and letting them go on the shuttle.
