Description:
------------
Today you can fetch the best matched language. But there's no way to fetch the rest of the languages. This would be very interesting in some cases -- eg. when there's no translation available for the best matched language one can fall back to the second best.

Attached is a small patch (against the current CVS version). Feel free to do whatever you like. I think it would be a great feature. ;)
