refactor(routing): Using Aura.Router for routing.

Assumed to be under: setup/coufig/routes.yaml
php yaml extension is required in order to read this file.
If I remember it correctly, we save the session cookie for a longer time (14 days) if the anonymous user decide to change the default language (detected by Zend and depending on the user agent of the browser) to a new language. Like that if this user come back to our website during the next 14 days he will not need to change the language again.
