Trying to tackle login without hardwiring users package provided in template...
Just using create view, nothing to test now, really.
Fixing import of TestCase class.
Updated Pillow dependency.
Switched to builtin user system, but retaining the provided views.
Still want the users app to be enabled.
Seems this is enough to use builtin users.
Always need latest Selenium, otherwise Firefox updates bork the tests.
Some extra changes not directly related to the user rewiring.
