Subject: [PATCH] [EGD-5287] Add Languages window

- add LanguagesWindow,
- add GetCurrentDisplayLanguageRequest message used for
  sending request from LanguagesModel,
- add GetCurrentDisplayLanguageResponse message sent by
  ApplicationManager and handled by ApplicationSettingsNew,
- add setFocusOnElement method in ListView so current
  display language can be focused on when entering
  LanguagesWindow
