Support for AsyncResponse/Suspended

[dnouls]

I'm using rest services which uses @suspended AsyncResponse to make the rest service into an asynchronous one. It would be nice if there was some support in GWTP to handle this.

It seems to me that supporting an empty emulated class for AsyncResponse should do the trick.

Note that I am using the dispatch rest delegated, where this support would be really useful since I want to reuse the jaxws interface as is.

Why tag me

Haha @Suspended is a Java annotation.
