The PROJECT_ROOT settings in settings_common.py does not seem to work outside of the
Django bundled WSGI server. Setting explicilty (insetad of using os.path.abspath).

You'll need to add PROJECT_ROOT and its dependent settings to your settings.py. See
the example settings file for a reference.

We should obivously revist this. There has to be a common way to get the Django
project root.
