I18n using path instead of cookies

[Kirens]

Currently the page uses cookies to store language preferences, if it's not hard to change I'd prefer it to be identified using paths instead (i.e. leading /sv/or /en/).

All the robots out there are currently angry with us that the page content changes.
But most importantly I think it's a good thing if this page expands and committees want to share their page to a group of students in a certain language.
