Missing Proxy Support in Requests/Transport/cURL.php

A Request via wp_remote_get() tries to connect directly to the external URL and returns "cURL error 28: Connection timed out after 10000 milliseconds". During research i found the reason in the Requests/Transport/cURL.php because it ignores the WP_PROXY settings from the config.php.

solution/workaround:

   //added
   curl_setopt( $this->handle, CURLOPT_PROXY, 'proxy.xxx.de' );
   curl_setopt( $this->handle, CURLOPT_PROXYPORT, 80 );

   curl_exec($this->handle);
