Pseudo-code this out a bit...

Just starting this is reminding me why I gave this up back during
zixaphir/appchan-x#242
build?
Unread.disconnect()
ThreadUpdater.disconnect()
Whoopse
Well, fuck. Looks like we're generating board indexes now. :D
Merge branch 'v3' into json

Conflicts:
	builds/4chan-X.user.js
	builds/crx/script.js
Apparently Main.clean() can break things pretty hard.

But only if on the same board? Weird.
More work on ThreadUpdater.disconnect()
Do you ever feel maybe you're actually dumb?
Try to consolidate
I don't know why that was under the thread conditional?
Fix .current
Reorder Index menu entries
Start working on getting index navigation from a thread working
Improve navigation between boards
Also allow navigation to indexes from boards.
;__;
Yeah, that wouldn't be good to happen, but..
Make the back and forward buttons kinda-sorta work
Small reflow
