Update Python Dependencies (#404)

* [requires.io] dependency update

* Server starts...

Various things are broken, but it runs!

* [requires.io] dependency update

* [requires.io] dependency update

* [requires.io] dependency update

* FIX: Broken migrations

* FIX: Update auth framework

* FIX: Correct static use in templates

* FIX: Fix supplier sort

* FIX: Remaining tests

* Revert "Disable password reset as temporary fix to vulnerability (#396)"

This reverts commit e0c6a56263.

# Conflicts:
#	RIGS/urls.py

* FIX: Fix broken newlining in PDFs

Introduced by a change in Django 2.1 'HTML rendered by form widgets no longer includes a closing slash on void elements, e.g. <br>. This is incompatible within XHTML, although some widgets already used aspects of HTML5 such as boolean attributes.'

* FIX: Fix some Django4 deprecation warnings

Why not...

* Refactor dependency file

Should now only include dependencies we actually use, not dependencies of dependencies and unused things

* Add newlines to the paperwork print test event

This will catch the error encountered in 79ec9214f9

* Swap to pycodestyle rather than pep8 in Travis

And eliminate W605 errors

* Bit too heavy handed with the dep purge there...

* Whoops, helps if one installs pycodestyle...

* FIX: Re-add overridden login view

* Better fix for previous commit

* FIX: Bloody smartquotes
