[Enhancement] Treat Playlists as TV shows

[MoeFwacky]

Feature Type
Scheduling Enhancement

Description
This feature would allow the addition of plex playlists (or possibly a manually created playlist xml) to be treated by pseudo channel the same as a tv show, so that each time an entry for the playlist shows up in the schedule, pseudo channel will schedule the next item from the playlist.

Use Case
This could be used to schedule a specific run of movies, for example the Marvel Cinematic Universe movies, once per week. Each week, when that item is called up on the schedule, it would schedule the next movie in the list. This could also be use to filter down a show with many episodes to a specific type of run, such as the Sideshow Bob episodes of the Simpsons or the Data episodes in Star Trek TNG.
