Added Direct Play and websocket improvements

* [backend]: Websocket now automatically tries to reconnect if connection was lost, up to 3 times.
* [backend]: Move more playback and resume logic to the backend, to avoid having it in multiple places within the QML. Regression: pausing playback sometimes halts the video player for an unknown reason.
* [playback]: Sailfin will try to play without the server transcoding, if possible.
* [ui]: added a debug page in the settings
