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.
Removed some non-matching fuzzy entries in mk, tr, zh_TW that prevented .mo regeneration by triggering "fatal errors" from msgfmt
Rebuilt all .mo files, fixing total breakage for four languages:
* it
* mk
* pt_BR
* vi
