* console-client/console.c: Include signal.h.
(signal_handler): New function.
(main): Register signal_handler to trap SIGTERM.

Hi,
I've been fiddling with running the console client as a system service
so it can be started and stopped with, e.g., "deco stop console" or
"service console start".
Could it have a signal handler added so the client exits cleanly on the
SIGTERM from these stop commands? It seems to lock up the display
without this.
Thanks.
David
