Django 1.9 changes

[bdero]

Let's keep track of things that can affect the code base when moving to 1.9.

Here's one:

• We should remove the django.request config when we upgrade: https://docs.djangoproject.com/en/1.9/releases/1.9/#changes-to-the-default-logging-configuration (thanks for spotting @justinabrahms)

So keeping track of issues went right to upgrading? Is there user value to this upgrade?

There are things that make django 1.9 nicer. self.client.force_login in testing, self.client.json being two in particular.
