Cookies top-level function does not exist, but shows up in docs

http://treq.readthedocs.org/en/latest/howto.html#cookies

The example here does not work on current master, since treq does not have "cookies" as a top level name. The closest thing I found was the treq.response._Response.cookies method.

I suspect this example is supposed to read:

    # ...
    def _get_jar(resp):
        jar = resp.cookies()
        # ...

I've replaced it with the response method.
