GoogleCurlIO class needs to use ipv4

[toby saunders]

I have just realised that the reason my api calls were taking 5+ minutes to return was the google curl io class not being set to use ipv4 - I inserted this:
        CURLOPT_IPRESOLVE => CURL_IPRESOLVE_V4,
to line 43 of GoogleCurlIO.php and everything now works nicely - just a heads up.

Did you really mean minutes or seconds. I have a similar problem but only 5+ seconds.

My issue was at least 5 minutes per api call - I guess the request is just floating around in ipv6 space waiting to get to google..
