* Socket communication class.

* $Socket = new HTTPSocket;
* echo $Socket->get('http://user:pass@somehost.com:2222/CMD_API_SOMEAPI?query=string&this=that');
*
* @author Phi1 'l0rdphi1' Stier <l0rdphi1@liquenox.net>
* @updates 2.7 and 2.8 by Victor Benincasa <vbenincasa @ gmail.com>
* @package HTTPSocket
