Our documentation building support has been updated to allow us to

generate docs against Django 1.11 and Python 3. The main Djblets

documentation needed to import models from Django apps that weren't yet

set up, causing various issues with autodoc generation. This was

resolved by setting up Django (needed in Django 1.7+) before any imports

could begin.
There were further errors at that point due to the lack of certain apps

in INSTALLED_APPS. These have been added.
Finally, the Makefiles for the doc packages now allow the Python version

to be overridden, letting us build on any version of Python we choose.

Successfully built all doc bundles using Python 2.7, 3.4, 3.5, and 3.6

across Django 1.6 and 1.11.
