Every developer is expected to have the same configuration from now on. The project must be added to the virtualenv's path. Security sensitive data for production use is stored in environment variables now.

To start a dev box:
django-admin.py runserver --settings=element43.settings.local
-or-
adjust DJANGO_SETTINGS_MODULE

To start in production, use:
django-admin.py runserver --settings=element43.settings.production
-or-
adjust DJANGO_SETTINGS_MODULE

Make sure to set the E43_SECRET_KEY and E43_RAVEN_URL env variables, too
