[GRASS5] Update for Spearfish sample data

[Markus Neteler]

Dear developers,

based on help and suggestion from Paul Kelly I have
updated the PROJ_INFO file in the Spearfish sample data set.

The ellipsoid and datum was wrong (was WGS84, but it is Clarke66).

Paul suggested:

The updated package is here:

http://mpa.itc.it/markus/tmp/spearfish_grass50data.tar.gz

please
 - try with any 5.0.x
 - try on various platforms

You may simply run
 g.region -l
which uses PROJ4 to report the current region in Lat/Long coordinates. 

If reports are ok, I'll move the file to
 http://grass.itc.it/data.html

Thanks,
(especially to Paul)
