Interlanguage links should not be rendered

[GreenReaper]

Some cross-namespace links ( [[:X:Y]] or [[X:Y]], or their piped variants) are actually interlanguage links, and should not be rendered.

It can probably be assumed that all links with a namespace that matches one on the ISO 639-1 list ( http://www.loc.gov/standards/iso639-2/php/code_list.php ) are interlanguage links.

Hi,
Thanks for the bugreport.
Altough namespace is not supported now, i just comitted a quick change to drop the boring language list, which is, indeed, useless. I didn't check for all the language linked by ISO, as it didn't match exactly, and rely on a regex at the end instead.
