In a module, when URL is not avialable for a shortcut, send None instead
of an implementation specific detail on how to show description. This
allows use to change the implementation of how description is shown
without changes to modules.
This can then be used by a privileged action to verify that packages
requested for installation are in fact valid. This slightly improves
security of those privileged actions.
Currently menu items are shown in alphabetical order in applications and
no clear order in system configuration. This is done using static
weights for menu items based on English names that does not work for
other locales.
Sorting can't be done at the time of adding menu items as users of
multiple locales may use the interface at the same time.
Implement a sorting mechanism based on existing order as well as labels
of menu item. This allows the flexiblity of grouping menu items in
future as it may be need for system configuration. In case of help menu
Remove sort order for all modules except for help menu as here we want
that specific order.
It has become confusing to reuse the name of the service for name of the
systemd unit file and firewall port. This has lead to the regression
that quassel, mumble and minetest can no longer open firewall ports.
Fix this by explicitly specifying ports all services.
- 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.
