This commit adds support for Django 1.9. As the template configuration options
changed with Django 1.8 and versions earlier than 1.8 aren't supported anymore
anyway by upstream, support for them is removed.
To have the Dockerfile still working, this commit also changes its logic so the
dependencies get directly installed via the requirements.txt from PyPI, which
will ensure that always matching versions of all dependencies are present (e.g.
the Django version).
This commit adds global authentication to binder to ensure that only valid
users are able to use it. This should enable binder to be used in
environemts where it's webfrontend is reachable for unauthenticated users as
well.
For setups where such a global authentication isn't desired it can be disabled
by simply removing the LoginRequiredMiddleware from the list of active
middlewares.
