 - Update descriptions
 - Update site_names
 - Update locale

Tests possible on http://smo.knowem.com/ using http://mf-geoadmin3.dev.bgdi.ch/ltpoa/ as url
Not sure, but isn't the locale de_CH (or something), because the description is in german?

Maybe we can leave it out as (in our case) it doesn't serve a purpose...
