[PATCH 09/19] tox: Turn deprecation notices into warnings

[Stephen Finucane]

Django does an excellent job of marking what features are going to
change in upcoming releases through extensive use of the 'warnings' module.

Pass the '-Werror' flag to 'manage.py' in tests, ensuring that any
warnings will result in exceptions instead. This should make upgrades a
mostly painless process going forward.
