[aprssig] jFindu Update

[AE5PL Lists]

It has come to my attention that QRZ has changed their display of
coordinates.  This broke the jFindu pages when looking up a callsign
that is not on APRS.  This has now been fixed (until the next time
QRZ.com changes the coordinate format).  Note that the coordinates from
QRZ.com are derived from the center of town if a street coordinate
cannot be found.  This has no affect on stations which are seen via
APRS-IS.
