Podcasts: Position in der Warteschlange einstellbar; Feeds nur noch auf dem Server holen (SW v51)

Warteschlange
- PodcastSettings: wohin neue Folgen kommen, getrennt für Hinzufügen von
  Hand (auch beim Abspielen einer Folge außerhalb der Warteschlange) und
  für automatisch eingereihte neue Folgen: ans Ende, an den Anfang oder
  nach die laufende Folge. Voreinstellung wie bisher (Hand: Ende,
  automatisch: Anfang). GET/POST /podcasts/settings/.
- queue/add nimmt auch mehrere Folgen (episode_ids), eine Position
  (where) und die laufende Folge (current_episode_id); ohne Angabe gilt
  die zuletzt angehörte, nicht fertige Folge als laufende.
- Positionen werden lückenlos neu durchnummeriert.

Feeds
- POST /podcasts/feeds/refresh-all/ aktualisiert alle Feeds des Nutzers
  auf dem Server: Downloads parallel, jede Feed-Adresse nur einmal (auch
  über Nutzer hinweg), mit Timeout; kürzlich aktualisierte werden
  übersprungen. Der stündliche Cron-Job nutzt dasselbe.
- GET /podcasts/state/ liefert Abos, Warteschlange, Inbox und
  Einstellungen in einer Antwort (für die Apps).
- Web: „↻ All“ ist eine Anfrage statt einer pro Feed; die stündliche
  Schleife im Browser lädt nur noch die Listen neu, statt jeden Feed
  selbst anzustoßen.
