Language updates - Consolidated into v4.00.15 (coming next 12-24 hours)

I'll be consolidating all language updates into v4.00.15, coming in the next 24 hours. So, any translators that want any more updates, submit them ;). Of course, they'll be later minor upgrades, but still this is an important build.

Some language updates have already been applied. However, I saw that I couldn't keep updating all day every time a new language update came in, so decided to do the remainder all at once.
