Before this commit:
website.page won't be rendered as translated items since it is not going though
a controller (route) enabling multilang. Website.page were not considered as
multilang items and no lang prefix were applied on link.
Now:
website.page will correcly handling translation.
In case of one route doesn't match a controller, it is now by default a route of
type multilang.
Add a new field auto_redirect_lang on website model to allow to deactive the
autoredirect of the lang optionnaly. The code will arrive after more tests.
