*: Make setup method part of App class for all apps
- Primary purpose is to complete the App API and allow for multiple apps to be
present in a module without a single clashing setup() method. Secondary
objective is to get rid of SetupHelper instance simple use App instance instead.

- This brings us closer to not needing to implement setup() method for some of
the typical apps.

- Remove default value None for old_version parameter.

  - A valid integer value is always passed to this call.

  - The value of None is undefined.

  - Simplifies the App API slightly.

- Drop setting 'pre', 'post' values to indicate the stage of setup for the App.

  - Simplifies the setup methods significantly. Eliminates a class of
  bugs (some of them seen earlier).

  - The UI can show a simple 'installing...' or progress spinner instead of
  individual stages.

  - There are currently many inconsistencies where many operations are not
  wrapped in helper.call() calls.
