draft for review

@mhoeber , @cahrens , @explorerleslie , @srpearce please review and comment, did I miss anything in the release that should be included?
https://openedx.atlassian.net/browse/STUD-1932. I also sent you an email. @talbs, where are the mockups for bulk publishing living? I was hoping to share with @lamagnifica so she could put a little teaser in this week's release notes.
