Variables

Oops! Thanks for the warning, it has been just a mistake caused by a partial reuse of another translation (Diary entries.index.in language title ("Diary Entries in %{language}") has language, while Diary entries.feed.language.description ("Recent diary entries from users of OpenStreetMap in %{language_name}") has language_name, quite a gotcha!). I fixed the two errors I found.

Thanks again.
