WIP: Replace persona
One option how to replace persona. I wanted to try it out, here is what I got so far. I will create a MR for postorius_standalone as well.
Note: django-user-accounts officially only supports django 1.8 and 1.9
The tests fail for 1.6 but pass for 1.7 I think we should drop both versions rather soon, because django is no longer maintaining them. Also django 1.10 will come out this summer which will definitely be incompatible to them.
Not everything that is displayed is working as it should (for instance the deletion of accounts) and some pages will have to be merged, but it's working
