Also changed some section names to use "messages" instead of "emails".
Since I haven't added Discord/Telegram/Matrix bot setup, I mentioned you
can do these later and linked to the setup guides. Sections related to
email mostly now depend on [messages]/enabled now too. Set password via
link has been added to password resets.
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.
