Upgrade site and modules to Django 2.2. Remove and replace obsolete
functionality with current equivalents. Update requirements to latest
versions where possible. Remove unused dependencies.
- This has the effect of bouncing people to the login page if they're
unauthenticated, rather than returning a 502 because 'home' doesn't
exist.
- If they're authenticated but don't have a speaker profile, send them
to the speaker profile create page rather than just to the
dashboard.
Closes#26
It's really annoying when you are adding a proposal and you hit tab and
end up on the link to the Hack website. There's no need for this and at
least on newer browsers we can pretty easily skip the links for tab.
Unfortunately because this is model text it generates migrations. As we
know these migrations don't actually do anything, so they are annoying
but not actually harmful.
So django keeps strict synchronization between its code and migrations
so that it can help generating new migrations. These are the additional
suggested migrations. A lot of these are a null effect, some are things
like transforming an unsigned integer to a signed integer. So not super
urgent on a small scale, but worth doing to keep django happy.
