Improve subtitles support

Add the content ID directly to the context menu when right clicking torrent links, or even an option to open the video directly in the external ts vlc player, OR improve subtitles support of the built-in player, in particular the ability to add subtitles, for example drag and drop subtitles directly on the video, because this is only available in the ts vlc player version. So either improve the way to open video into the TS player (right click -> conted ID or directly play into ts player), or improve subtitles support for magic player (drag&drop or browse file on the computer)
