Customize Django Admin

[amakarudze]

Django-suit used to give us a nice user interface. Now that we have removed it due to it not being compatible with supported version of Django, that is, version 2.2 +, we need to work on customizing the interface once the upgrade to Django 3.2 is complete.

If it's just for a nicer appearance then this is a great package

Thanks @marksweb. Will check it out.

We seem to be having some issues in Sentry, I guess due to changes in the admin. It seems some functionality was broken. I managed to resolve 2 which were a result of data errors but some may need more investigation. If you have the time of course. Thanks again for all your work @marksweb!

@amakarudze From what I've seen, the changes aren't really from changes to admin, they're from the 2.2 upgrade.

I've fixed a couple of things just now. Essentially it's areas of the application which aren't tested - so admin is a big one with what I've updated. A reverse() for a URL in admin was wrong, and a widget being used for an HTML field is out of date and doesn't work with django 2.2 so I've replaced it with something new.

I think there will be more to do for a while yet, but I'll keep chipping away 👍

Thanks @marksweb for looking into this quickly. Yes, that is the challenge with untested code I guess. Yes, it seems there will be a lot to do for a while. Thanks for all your work.

Sorry all these issues delay me getting to #667 pull request but I will get to it when organizers and Claire can at least do their work. Thanks again @marksweb.

Do we want just some color changes to match the brand or does this include UX changes to make event management easier for organizers? We can start with some tweaks on Django admin itself (modifying templates and CSS, shouldn't be too hard) and go from there.
