[progress-events] Progress Events is a W3C Recommendation

[Arthur Barstow]

Congratulations to Anne, Jungkee and Chaals on the publication of a 
Progress Events Recommendation 
<http://www.w3.org/TR/2014/REC-progress-events-20140211/ >.

(I updated this spec's PubStatus data to state that no additional work 
is planned and that the feature is now part of XHR.)
