Thanks for opening this originally, and sorry it took so long to get to!

I've made a tweak which still incorporates your other valuable changes but mainly re-instates the previous syntax and more common pattern of passing the respose directly to context.done. This seems to follow the Azure reference a bit more closely. I've also rebased it on the current master, tested it both with the existing tests and locally using the Azure command line tools.

Hopefully this will solve the problem with Azure functions; we'll get this released soon. Thanks again!
