FIX: Webui ping problem

For fixing a ping problem with FOG 0.32.

In /var/www/fog/management/ajax/host.ping.php at line 48 :

	try
	{
		$ip = gethostbyname($_GET["ping"]);
		
		if ($ip != $_GET["ping"])
		{
			/* FOG 0.32
			$ping = new Ping($ip);
			if ($ping->execute())
			{
				// Ping Success!
				echo "1";
			}
			else
			{
				// Ping failed
				echo "0";
			}
			*/
			/* Aruhuno's contrib */
			$socket = fsockopen($ip, 20, $codeErreur, $msgErreur, 0.01);
			if ($codeErreur != 111)
			{
				echo "0";
			}
			else
			{
				echo "1";
			}
		}
		else
		{
			echo "Unable to resolve hostname: $ip";
		}
	}

It is a do-it-yourself, but that works, while waiting for the version 0.33.
