[mod_python] getting cookies from the response

Why not create a wrapper to Cookie.add_cookie() that, in addition to
writing the cookie, also saves it to a dictionary you create at
req.cookies_written?  That way, unless you are interfacing with other
cookie-writing code, you can always check which cookies you have
already placed in the outgoing headers.
