After the recent cleanup, pagekite no longer shows description before
installation. Only after installation does it show the insturctions
about why it is needed. Also in the description {box_name} is not
substituted and there are incorrect escape sequences.
Revert this earlier change that causes these regressions.
- 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)
- Merge actions/pagekite_util.py into plinth/modules/pagekite/util.py.
- Rename plinth/modules/pagekite/util.py to utils.py.
- Add python-augeus as dependency.
- Move actions/util.py to plinth/action_utils.py and update services
that use it.
- Rename _run() method to run() as it is being used publicly.
- Import the utils in a more conventional manner.
- Move all python2 bits to python3.
