I've started putting in some language support...
now when you search it specifies the language
as well as the AID in the link, and when you then
view the article it displays it with language-specific
text as well... though at the moment the languages
are limited to english and my vandal job on spanish
(me just making up odd versions of the english words).
apologies to any spanish speaking people!

At the moment if no language is specified everything
defaults to english, which I thought to be sensible
because mandarin chinese aside it's the world's most
spoken language.
