Merge a17t-redesign, kinda ts-ify setup.js

the web ui has been redesigned with the a17t toolkit, which imo looks a
lot better than bootstrap. This also brought a complete rework of the
web code, which now makes a lot more sense hopefully. the setup page is
still stuck with bootstrap, its not much of a priority but i'll rewrite
it eventually.
