Made DummyTranscription update phonetics

- This way we prevent confusion between 'PLAY' and 'missing',
  where 'missing' indicates a DummyTranscription.
- 'missing' is currently not translated.
Fixed handling of spLang

- Made it possible to switch from a specific spLang back to none/current translation.
- Made sure word entries in WordMenuView and LanguageView are translated with the current spLang.
