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

Routing file is defined by the app.
Assumed to be under: setup/coufig/routes.yaml
php yaml extension is required in order to read this file.
I saw that. The code is (and was) inconsistent. None of these messages in the exceptions should be translated.
I left it as it was to minimize the changes introduced by this refactoring, but we should eventually get rid of this pattern and make sure no one relies on it. I believe that it was added by jfouilhe.
