Login/Logout jetzt in der Navi! News-Link ergänzt und Weiterleitungen gefixt (mit /bibarts/). Fehler nach Login behoben.

- pwRequirementCheck und checkDoublePw aus Controller ins Model
- Alle Passwort- und E-Mail-Validierungen jetzt zentral im Model
- Controller macht nur noch Request/Response Handling
- Saubere MVC-Trennung
