Support live streams
Now the type of a video is defined when trying to play a video so that live streams (.m3u8) are directly played by Kodi (no download required).
We are able to know if a video is live from the response of the "list"
REST API but it was decided to ignore this information in order to have
a single action to play video (whether it is live or not).
The goal was to keep the API of the add-on as simple as possible so that
externel users only have to call the add-on's API with the ID of a
video, without having to add the type of the video.
The information about the type of the video will anyway be available in
the response used to get the URL of a video so this solution does not
impact the performance.
