There should be a better way to include the see the 'main_app' and 'katello' helpers without restoring to meta-programming.  In the console, 'main_app' and 'katello' are instances of class `ActionDispatch::Routing::RoutesProxy`.  This are automatically available in controllers and views, but not in a service class such as Menu::Item.  I tried `include AbstractController::Railties::RoutesHelpers` but didn't work.
