Moved the res.status(404) from the renderPage method to the err404 method, which is the actual error handler (why was it added to the renderPage method in the first place?)
Improved multi-language support, there can now be different dictionaries loaded at the same time and the correct dictionary is (at least for now) determined by the users request header 'accept-language' attribute. Also changed the error pages to support this new feature.
Merge branch 'master' of https://github.com/kollemate/kolledata
