Add unplayed episode count and refresh number in real time

[1hitsong]

Changes

Consistently adds unplayed episode counts to TV Series and TV Seasons across the channel - libraries, series/season details, collections, search results, etc.

Refreshes the unplayed episode counts as data changes. For example, search for a TV series using the general search on the home screen. Click on the series and drill down to a single episode. Mark the episode watched. As you press the back button on your report, each screen's unplayed play count should update as your navigate back through the screens.

Additionally, using the item option menu will also update the unplayed count / played check mark display.

The disable unplayed count setting is honored.

Found a corner case. Not sure if it's a legit case though.

1. Enable "Rewatching Next Up" under Settings, User Interface, General
2. Go to a show you've completed
3. Mark one show unwatched
4. Notice show on the Home Screen "Next Up" has a check and not the number "1"

How are you seeing a series in the Next Up section? Isn't it single episodes?

Can you post a screenshot? I'm having a hard time recreating the situation.

It is a single episode. But it has a checkmark. I'd expect nothing (like the rest of the items in Next Up) or a "1"

My guess is there is some logic that says "have you watched everything? put a checkmark". And by re-enabling "allow rewatched to show up in Next Up", you get the checkmark.

Does it show the checkmark on web?

The API returns a property for items called "played" and if it's true, the checkmark is displayed. I'm guessing since it's a "re-watch" the API is reporting is as played.

Yep... I enabled Re-Watching on the web client and it does the same 👍
