- Weather unterstützt jetzt Inline-Query!

ACHTUNG: Falls noch Daten im Cache hängen (unter telegram:cache:weather in Redis, aber NUR die Koordinaten, nicht die Städtenamen!), diese bitte LÖSCHEN, da jetzt Hashes benutzt werden, um mehr Daten zu cachen (für den Inline-Mode), anstatt simple Keys
- Fixe Caching für Hashes (am besten ohne TTL verwenden, TODO: fixen)
