Bay's embedded controller rewrite

Created by: Duny-

I did my best to port that shit without breaking everything. It's not perfect but it's functional. Embedded controllers now have sexy nanoUIs with pressure updates in real time, HOW EXCITING! Most importantly they're easier to map, more clean and I find them more responsive. Everything worked fine during my tests but better review the code because it's the first time I really had to deal with byond code without just copypasta'in and renaming a few things and I'm not sure about pretty much everything I did.
