Rick Eyre 73e8300de5 Bug 833382 - Implement WebVTTLoadListener r=cpearce,bz
- Implemented WebVTTLoadListener to manage the webvtt parser.
- TextTrackCue now handles the conversion of webvtt nodes to
  anonymous content which will be displayed on the video div
  overlay.
- HTMLTrackElement manages the lifetime of the WebVTTLoadListener.
