Make it possible to use an httptest.ResponseRecorder where a restful.Response is expected

[eggpi]

It seems to be already possible to mock a restful.Request since it simply wraps a http.Request, which in turn can be hand-crafted while testing. However, it doesn't seem to be possible to wrap a httptest.ResponseRecording in a restful.Response in order to examine what my handlers have done to it.

To the examples, I added a file that shows how to test your handler using a httptest.ResponseRecorder

Thank you very much! :)
