- Reduce the number of specialized messages to ease localization and clear way
for generalized configuration change handler.
Tests:
- Update the one or two configuration setting at the same time and notice that a
single message is shown.
- When no setting is changed and form is submitted, 'settings unchanged' message
is shown.
- Raise error when enabling/disable auto updates and notice a proper HTML error
shown. When other setting is also updated, then one error and one success
message is shown.
