With the new routes, all pages are not all at the same folder level anymore
(e.g. /shaare and /shaare/123), so we can't just use './' everywhere.
The most consistent way to handle this is to prefix all path with the proper variable,
and handle the actual path in controllers.
* translation system and unit tests
* Translations everywhere
Dont use translation merge
It is not available with PHP builtin gettext, so it would have lead to inconsistency.
