When signing up, the user is given a pin code which they send to a
telegram bot. This provides user verification, but more importantly
allows the bot to message the user, as the Telegram API requires the
user to interact with the bot before it can do the opposite.
The bot should recognize the correct language, but a /lang command is
also provided to change it.
The verification process is pretty much functional but ui is still
broken, and it isn't properly integrated yet.
this will add an optional validity period to users, where their account
will be disabled (or deleted) a specified amount of time after they
created it.
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.
