Two additions to gcs.override.csv needed to fix KKJ and ETRS89

I reported this a long time ago on the list but did not follow it through. See ​http://lists.maptools.org/pipermail/geotiff/2008-October/000515.html

The parameters to KKJ can be found in a recommendation text (PDF) linked to page ​http://www.jhs-suositukset.fi/web/guest/jhs/recommendations/153

The two new lines should be:

4123,KKJ,6123,Kartastokoordinaattijärjestelmä 1966,6123,9122,7022,8901,1,0,6422,9606,-96.0617,-82.4278,-121.7435,4.80107,0.34543,-1.37646,1.4964
4258,ETRS89,6258,European Terrestrial Reference System 1989,6258,9122,7019,8901,1,0,6422,9603,0,0,0,0,0,0,0,0

As part of a recent upgrade, a datum shift was selected for KKJ by build_pcs.py. However, operation 1639 was picked and the EPSG notes indicate that operation 10099 superceeds this. 10099 has the parameters suggested above by Ari. I have updated the datum shift preferences and generated files to reflect this (r1821).

ETRS89 is now using the 0,0,0 shift from the EPSG file as suggested above.

Hmm, I botched that. New commit to clean up (r1822).
