- 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)
The Service object now offers handling services on a system level,
and gathering information whether it's enabled or running.
New methods: enable, disable, is_enabled, is_running;
For this it needs the correct (system-level) service name.
All of the methods can be overridden/customized.
This changes all modules to the new Service object and deletes
action scripts that are not required anymore.
- Installing dbcommon-pgsql and not install dbcommon-mysql does not
ensure that PostgreSQL is selected as the database for the
application. Set a debconf value to force selection of PostgreSQL.
- Minor styling fixes.
