Report playback progress and resume items

[Playback]: New: playback progress is reported to the Jellyfin server.
[Playback]: New: resume partly played items or start playing from the beginning if desired.

I also had to make some changes to the VideoPlayer, because the VideoHUD
got locked up when the player changed status from Buffering to Buffered
too quickly in succession, which occurs when trying to seek directly
after the application is able to.
