Resolve "clean configuration"
All smasch configuration options that could be moved to ConfigurationItem were migrated. As a result local_settings.py is small and clean - configuration options are available in GUI.
Before deploying it in production these issues must be resolved: #359 (closed), #334 (closed) - otherwise we might expose sensitive information which we don't need to provide to end user.
Closes #343 (closed)
