If a param 'redirect_on_finish' is given to the applet, redirect to that URL when we've finished getting down. This allows us to have some javascript on that redirected page close the window getdown was in. I'd prefer to do this with the javascript bridge from the applet into the browser, but calling window.close() from the applet doesn't seem to do anything
