Updated the example application to reflect today's snapshots which introduce some breaking changes to the API.

Thanks for the great blog post! 

I introduced some breaking changes today to the Reactor API so I updated your sample code to reflect those changes. They're fairly superficial (just changing some method names) but I did make one change to the way Promises are being created. I used the `success` method to create a fulfilled Promise since the accept method is now only on the Deferred object rather than on the Promise itself (part of another recent change that separates the Promise API's publishing from consuming).
