[ticket/13654] Moving reporting into controller

Moving report.php's content into different services and controllers to
better comply with the MVC model.

Also implementing:
 * Replacement for reasons_display()
 * Adding assign_meta_refresh_var() to \controller\helper
 * Adding separate routes for easy configuration
 * Updating unit tests to expect to correct results
 * Add BC tests
