Qml based Aurorae themes can provided a ui file which gets loaded at
runtime. Obviously such a ui file is not translated. This introduces
quite a hack to load the translated strings.
First of all a new property is added to the service file for
specifying the translation domain to be used for the config UI. If
such a translation domain is set we extract all string properties of
the loaded UI and pass them through ki18nd.
