Publicize & Open Graph Enhancements
Merge with WordPress.com

Adds some new classes that can be used to analyze what a post is made up of (video, gallery, etc).
Adds a new piece to Jetpack Publicize that will add some enhanced open graph tags for Video, etc so publicized Jetpack posts can get the same goodness as WordPress.com got with the recent Facebook work.
