fix long_url of digg.com

[GoogleCodeExporter]

What happened?
when calling long_url for digg.com, and the real long url is also on that
site, the function returns a relative path and could not be accessed correctly.

here is my small fix:

in function long_url, before returning the $url_long:

if (substr($url_long,0,7) !== "http://")
    {
        preg_match("/^(http:\/\/)?([^\/]+)/i", $shortURL, $matches);
        $host = $matches[2];
        $url_long="http://".$host."/".$url_long;
    }

    {
        preg_match("/^(http:\/\/)?([^\/]+)/i", $shortURL, $matches);
        $host = $matches[2];
        $url_long="http://".$host."/".$url_long;
    }
