v1.5.1

• Support video and webvtt tracks.
  • Track and video files must all share the same base file name (ex: "video.mp4", "video.vtt")
    • Theme now supports the following values for track metadata:
      • Dublin Core: Type ("subtitles", "captions", etc)
      • Dublin Core: Language (the language code for the track)
      • Dublin Core: Title (the label for the track)
    • Multiple language tracks are supported. They still must share the same base file name as the video: the user differentiates between them using their Dublin Core metadata.
• Update npm dependencies.
