- 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.
