Removed require.js scheme since it forces async event driven model, this model does not work with the comm/widget communication model. We need to be able to load the dependencies before we send the show() message to the widget manager. Otherwise a race condition will exist where the widget manager may recieve the show message before the dependencies have been loaded (happened almost every time).
