* Update vtt.js to the newest version which has the capability of reporting back ParserErrors. * Update the update-vtt.js script a bit as well since the symbols that it exports have changed a bit since the last import. Some of the general information it outputs has since changed as well like where the repo exists. * Update WebVTTListener to set the track readiness state to 'failed to load' if the WebVTT file is not loaded correctly.
