* found some duplication in the large "Commands:" messages. Manually removed from the pot file, and then updated. Have to ask someone if I can just rebuild the complete pot from scratch, or if --join-existing is always needed (and if so, why). File appears to contain at least some dirt.
scripts/update_translations.php now pulls updated files from TranslateWiki and merges them to an updated master.
Note that the .po files exported from TranslateWiki do lose some of the old manual comments for now.
