[Xastir] Did the NWS pull a fast one - Shapefile data

[David Flood]

I think that despite the filename being the same, the NWS pulled a fast one
and silently updated the z_10oc19.dbf file.

I did a git pull today and it pulled in a new get-NWSDATA script so I went
ahead and ran it after a full compile.  It's reporting that there isn't a
dbfawk signature match for that NWS file.

I took a look at the Wiki but I can't tell which file(s) in the dbfwak
database are used for the z_ files so I'm having trouble rolling my own.
