If the plug-in is working correctly, a click on the "Call fortytwo()" button should open a popup dialog containing 42 and a click on the "Call helloworld()" button should open a popup dialog containing hello, world..
Note: For the purposes of contest issue #55, the actual expected result will be a "Method invocation failed" dialog when the "Call helloworld()" button is clicked. The browser should continue to work properly after the dialog is closed. The "Call fortytwo()" button is not connected to any code, and should do nothing when clicked.
