Add support for cinema mode (#1305)

## Description
Adds support for cinema mode, which is enabled by default.

When enabled and if starting playback from the beginning, the server is
queried for any "intros", ie prerolls or trailers, to play first. These
are shown in the queue and can be skipped if desired.

The server has to provide the intros, so a plugin like
https://github.com/jellyfin/jellyfin-plugin-intros or
https://github.com/CherryFloors/jellyfin-plugin-cinemamode is required
server-side.

### Related issues
Closes #418
Closes #1180

### Testing
Emulator and server w/
https://github.com/CherryFloors/jellyfin-plugin-cinemamode
