Fixed

• [Vosk] Fix checking whether the model is already downloaded
• [Vosk] Keep showing the download icon when no model is available for the current user locale

Development

• Now dicio-sentences-compiler accepts word variations, such as <e|g?>mail, which matches "mail", "email" and "gmail". This reduces the amount of words that need to be written in .dslf files for some languages. DicioTeam/dicio-sentences-compiler#7 DicioTeam/dicio-skill#4
