Subject: [PATCH] Tooltip explaining callsign-based destination lookup

Hovering the dotted-underlined "callsign" in the Destination label
on /path now surfaces a tooltip explaining that callsign lookup
queries QRZ for the licensee's mailing address and geocodes it, so
the resulting position may differ from where the station actually
operates. Gives users a reason to enter a grid directly when they
know it's more accurate than a QRZ address.
