[webvtt] Pull Request: Modify the parsing rule to set the cue's identifier.

alastor0325 has just submitted a new pull request for 
https://github.com/w3c/webvtt:

== Modify the parsing rule to set the cue's identifier. ==
According to #310, the parser doesn't set the cue identifier to 
anything but the empty string. 
The fix is to set the cue identifier to buffer on cue creation.

@zcorpan, could you help me review this patch?
Thanks!
