Update to hapi 3.x

This is really a "pull request as question."

I'm interested in using the hapi 3.0.0 release, but can't find information on what else does/doesn't work with it in the Spumko ecosystem.  For yar, the tests pass with hapi@3.0.0.  Does this mean the two can be used together?

I've got the same question about travelogue.  Thanks for any tips.  Ok by me if this gets closed and the answer is "don't use hapi 3 yet."
