#10 Langauge stat

[Frank Dahlin]

Language only register first two letters from
HTTP_ACCEPT_LANGUAGE, if more languages is
specified these are ignored. The stat should consider all
accepted languages.

Eg. if HTTP_ACCEPT_LANGUAGE is da,en only da is
found in stat and the owner of the site might consider
changing the language of his site to danish - a full stat of
HTTP_ACCEPT_LANGUAGE might show that english
was ok for his site.
