Blogs: eigene Ordner (mehrere je Blog, umbenennen, auflösen), Lesefortschritt

- Source.folders (Etiketten, Groß/Klein egal, max. 40 Zeichen); die bisherige
  Kategorie eines Blogs wird sein erster Ordner (Migration)
- /feeds/folders/rename/ und /dissolve/; in den Blog-Einstellungen Häkchen je
  Ordner plus „Neuer Ordner“; langer Druck/Rechtsklick auf einen Ordner: öffnen,
  umbenennen, auflösen; Ordnerliste in „Feeds verwalten“
- Lesefortschritt je Post (Item.progress, geräteübergreifend): die Leseansicht
  springt zurück an die Stelle, ab 90 % gilt ein Blogpost als gelesen (Nachrichten
  weiter beim Öffnen); Fortschrittsbalken und „Weiterlesen“ oben in den Blogs
- sw v95
