[webvtt] Dispatch Text
Track Cue enter and exit events
When their display state changes, individual TextTrackCue objects should queue 'enter' and 'exit' events when their display state changes as playback advances. http://www.whatwg.org/specs/web-apps/current-work/#cue-events
I'll get a patch ready for this as well since we're tackling cuechange events now.

I'm looking into this since I need this event to be implemented. Just firing the events is easy, but doing it in the exact order required by the spec probably requires that we move this logic to HTMLMediaElement. I'm planning to implement this in the relatively inefficient way described by the spec (generate three lists of cues, generate events, sort events, sort tracks, etc.). We can optimize after it's correct.  https://html.spec.whatwg.org/multipage/embedded-content.html#time-marches-on
