German TTS: Add proper article to street name

- Add article detection based on street name ending. E.g. auf die Hauptstrasse, auf den Feldweg.
- Removal of Semicolon in Destination Name. Prevents Instructions like: "Richtung München Semicolon Nürnberg"
- Changed order of Ref and Street Name. If available Street Name is spoken first. Low Level Refs like Staats and Kreisstrassen are no help in routing since not labeled.
