- adapted all modules to not use views.ConfigurationView anymore
- removed templates that are not needed anymore
- no more implicit 'enabled' and 'get_status' functions in __init__.py files
- (more coherent/explicit use of Django functionality)
- PEP8 fixes.
- Don't need to disable .socket and .service. Disabling .service will
take care of disabling both.
- Update the introduction message.
- Add prefix to form so that it can potentially be mixed with other
forms.
