*
* Serverstatus class
*
* Tested and working in PHP5, PHP6
* Only tested with Call of Duty serie.
* Connects to a server an retrieves the data.
*
* @throws ServerException
*
* Known bugs:
*  - Sometimes (random) the server returns 'disconnect' as data.
*    Then the script just dies for unknown reasons (???)*
*
* Version 2.0
*   Class implementation
*
*   CHANGELOG
*     1.0      - 5 May 2004
*                Made by =(.T.T.B.)= Spikey (http://www.phphulp.nl/php/scripts/7/145/)
*     1.1, 1.2 - 13 May 2004
*                http://www.phphulp.nl/php/scripts/7/146/
