all theme functionality is now in theme.ts, and the tab stuff has been
changed a little but kept in admin as it won't be in use anywhere else
for the time being.
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.
