Some localisations for light-locker-settings are availlable in the package but not used.
For instance, for french, the amount of time displayed dynamically for sliders is effectively
translated, but the that's all whereas the light-locker-settings.mo is fully translated. I managed
to get the translation work by adding the command :

self.builder.set_translation_domain ('light-locker-settings')

right after the :

self.builder = Gtk.Builder()
