Checked in the changes to packet-isup.c with the change to put "ISUP:" in
front off the ISUP message type.
Hmmm, is this necessary? Or could it be made a preference (like
'isup_show_cic_in_info')?
I generally prefer the Info column to be cleaner (since when viewing
ISUP over MTP3 or M3UA putting "ISUP:" in the Info column is
redundant--you can see the protocol in the Protocol column).
