Reviewers

On systems such as Fedora where older versions of Django are
installed as alternative versions (and not directly importable),
we need to ensure that we are importing exactly the right version
of the Django modules.

This patch adds a new variable in the reviewboard __init__.py that is
imported by both setup.py and build-media.py to ensure that they
are both relying on the same version of Django.

Built successfully on Fedora.
