TabbedLanguages.js

Ah, sorry, there was a bug in the script. It should work now.

(By the way, is putting the page title in the L2 headers next to the language name standard over there now? If so, that's likely to cause some issues with the script...)

I tried again, by removing the title of the page next to {{Lingvo}}, then emptying the cache of the browser and by adding "&action=purge" to the path index.php to be sure, but I do not see any results then. Maybe I didn't do what I should.
