Проверка статуса пользователя в Skype

Статус Skype в разных форматах:

• XML output URI: http://mystatus.skype.com/skypename.xml
• NUM output URI: http://mystatus.skype.com/skypename.num
• TXT output URI: http://mystatus.skype.com/skypename.txt
• Image output URI: http://mystatus.skype.com/skypename

/**
* According to Skype documentation ( https://developer.skype.com/Docs/Web?action=AttachFile&do=get&target=2006-06-06skypewebdevnotes.pdf ),
* we can check skype status through http://mystatus.skype.com/<username>.<ext>
* Available <ext> are :
* .xml (returns complete xml with status in 12 languages and number)
* .txt (returns a string (warning : language depends on client configuration!) )
* .num (return only status number [1 = offline, 2 = online, 0 = account doesn't exist]
* <non> (return basic image)
*
* This class takes only .num, as it's very easy to use it. It checks only if it doesn't match "1". others are considered as online.
* If status == 0, account doesn't exist, so we return false.
* It can give other status as simple numbers if you wish (there's a function for this inside the class).
*
* Requiered :
* 1- fopen for external files support
* 2- well, nothing else I guess ;)
