[CLOSED PR] Accessory slot.

[DisturbHerb]

I (personally) don't like the idea of a cosmetic-only slot very much, if it's meant to be solely for aesthetic purposes I think it takes up valuable UI and HUD real estate for not a lot of gain. There's lots of cosmetic items that go in other slots, but there's also lots of useful stuff, and thus seeing someone wear a cosmetic item still relays the info to you; if you see someone wearing a jacket you know they don't have armor on for instance. The mob sprites give you a *lot* of info and I think adding more noise to them without any real implications mechanically isn't good.

Given that this PR currently only adds the slot itself - and nothing that actually fits into it - it's something worth working on. The first use-case that I thought of, of course, was to have a storage space for my stethoscope that wasn't just my pocket or backpack. Maybe "accessory" isn't the best name to give it, but it is supposed to be a place for worn items that don't (in my opinion) fit anywhere else. Scarves really shouldn't take up the entire suit slot.

With stats/useful stuff to wear in the slot I'd like it *more*, though I'm not really sure the PR is meant to be like that. I think it would be kinda a bummer if stuff like scarves (the best use-case for this slot probably) didn't give a bit of cold res, it's a cute attention to detail thing that I like in this sorta game. Bear in mind of course that I'm just Me and only speaking to my own opinions (and not any other admin's thoughts) of course. I do think the HUD element itself fits in quite well with the others and are placed in good spots.

Yeah, that is something that'd be great to have. It's just that I personally feel that some of the cosmetic items that currently go in the suit slot shouldn't take up the whole thing, such as the scarves we already have. If we moved all our scarves over to the accessory slot and gave them cold resistance, that'd be great.

Another silly idea I had was to turn security badges into accessories and then give a vanishingly low chance for it to catch a single kinetic bullet (which would then destroy the badge or render it unable to catch any more) without it dealing damage.
