A ParameterStatus packet can be sent by the server to notify the client that a system parameter has changed, either because of a direct action by the user (like a set name=value command), or for any other reason.
String packetType: "ParameterStatus"
String parameterName : the name of the parameter whose value has changed
String parameterValue : the reported new value of the parameter. Changing this changes nothing on the server, only what will be reported to the client.
