* Use English as source, instead of 'untranslated'
* Use ja (instead of jp) for Japanese, as supported by Transifex
* Use English as source for Qt generic strings
Note that qtgeneric is distribruted (with another name) along with the
Qt toolkit. It might make more sense to use their translation instead
of doing it manually. Not all languages are available. Turkish is an
example where we might have more translations.
