[clug] Launch gnome-terminal to launch daemon process

[Hal Ashburner]

Runs fine if you just run it from a terminal. No different in input or
output so I'd agree that's unlikely to be a cause.

This:

trap "date > /tmp/signal-test" INT HUP QUIT TERM
cmd="exec /usr/bin/python /opt/ark/bin/hgview &"
eval $cmd

also didn't make any difference which makes sense to me as the scrip
will exit very quickly after launching the python so won't be around
to trap the signals.
