Add option to mark TV episodes as watched/not watched

[dd900]

Is your feature request related to a problem? Please describe

Sometimes after watching a show it still shows up in next up or continue watching. I have to use PC or Android client to mark the show as watched.

Describe the solution you'd like

A menu option to mark the selected show as watched/not watched from both the home screen and the show/episode screens.

Additional context

The home screen options (* menu) should be reconfigured so that if a show or movie is highlighted it will show a menu that corresponds to that show/movie. If the main categories (Movies, TV, Collections, etc.) are highlighted then show the main settings menu.
