[OZAPRS] T2 Server "heartbeat"

It's just to make sure that you are still connected - and to get around
state timeouts on dodgy routers (netgear DG834's for example have a 60
second timeout on NAT sessions - so if no data flows across a connection
for 60 seconds, it drops it from the firewall state table, and disconnects
you)  - also stops the TCP connection list on the APRSD from filling up
with lost connections as well.

Not sure if you can filter it from the terminal window, as I think that
just dumps all data received across any open connections (RF or TCP)
