Updating translations for 2.9.2 release

[Vadim Zeitlin]

Hello,

We're going to release 2.9.2 soon and while it's still only a development
release, we're getting closer to the final 3.0 too and so it would be nice
if the translations could be updated for the current svn HEAD. Of course,
several of them are already up to date (Czech, Dutch, German, Italian,
Japanese, Polish, Brazilian Portuguese, Romanian, Slovenian, Turkish,
Ukrainian and Vietnamese) and a few more are reasonably close (French,
Korean, Malay, Portuguese, Spanish and Swedish all are above 90%) but it
would still be nice if you could look at them.

Thanks in advance!
