* Service multiplexing
Broadcaster call signature is changed to
broadcaster host service [message]
to acommodate multiple sevices listening on the same port for
broadcast information.
* Receiver Loop
Listener now loops infinitely instead of returning after the first
packet. For each packet with the content service[,message] the
programm
service [message]
will be executed. Upward directory traversal is prohibited (and
detected).
To prevent DoS only one service program runs concurrently.
* Common.h
Port numbers and maximum message sizes are now stored in
common.h. Broascaster respects max. message size.
