Subject: - Added a 20ms delay between each command sent from the client to
 LCDproc. - Better managed errors. Now the client resets the error counter
 every successful communication session with LCDproc (before was a global
 counter). The error counter is managed inside the client
 (lcdproc_client.php). - Because of the above change, now the "client script"
 (lcdclient.sh) do not cycle anymore.
