Apparently, this file hasn't received the cleaned up source strings for
weather scenarios obtained since FGMeta commit c2a241c35[1]. The file
committed here was produced by simply running
fg-update-translation-files with what we currently have in FGData. I've
ignored changes to the other FlightGear-nonQt.xlf files because they
seem to all boil down to a modification of the order in which XML
attributes are given (what a PITA!).
