ICQ UIN:


/**
* According to ICQ website, we can have this kind of picture: 
* "http://status.icq.com/online.gif?icq=<account>&img=26"
* As they seems to be some nasty boys and have closed normal approche,
* We have to use sockets (and as it's a bit cold in here, it's
* better with sockets.. well.. ok)
* So, requiered :
* 1- Sockets support for your PHP.
* 2- hmm... that's all :]
