Introduce component architecture and menu component
- Introduce base class for all apps that will contain components. With
  unittests.

- Introduce base classes for components. With unittests.

- Turn Menu class into an app component.

  - Further cleanup Menu class.

  - Update tests.

  - Maintain a global list of menu items and look them up easily. Generalize
    such that subsubmenus can later be merged into Menu class.

  - Cleanup scope of main menu initialization.

  - Use None instead of empty strings for various values. Ensure that
    printing short_description does not show 'None' in output.

  - Use enable/disable instead of promote/demote.

- Use menu component in all apps.
