Job Scheduler XML answer is empty in case of the security level of the client is insufficient

For example:

If the host which sends the Job Scheduler a command (the client) via TCP/UDP, the XML answer is empty, if the security level of that client is lower than level "info" for the command show_state. The security level of a client is assigend by the "allowed_host" element of the "security" element in the Job Scheduler main configuration file.
