Show favourites of other readers

[The4thLaw]

In the series view, the favourites of the current reader are currently displayed.

It would be good if the favourites of other readers would also be shown.

• On the series view, the text would be one of:
  • This album is one of your favourites and also a favourite of: (accent, heart)
  • This album is a favourite of: (no accent, heart outline)
• On the album view, it would be the same but the JavaScript handling fave/unfave should take care of displaying one or the other text.

This will require reviewing the way the reader context is set, to be able to get the favourites of other readers.

TBD whether this is actually useful.

There could also be a configuration property do display that text inline or as tooltip (TBD).
