/** 
* This is an attempt to check online status for users. 
* Method: 
* first we ping an onlinestatus server. If response time is too long, or if it's down, we change. 
* Time response has to be under 1s. 
* 
* You can find some address here: http://www.onlinestatus.org/usage.php 
* 
* I've seen that IP addresses are faster than "human" addresses, as we don't have to resolve these adresses. 
* 
* getStatus() sets status to : 
* 0 : offline 
* 1 : online 
* 2 : unknown 
* 
* isOnline() returns true only if status is 1 
* 
* Requiered: 
* 1- fsockopen support
