 notes:
  * to install, apply the diff and extract images in wp-includes-images.zip
 into wp-includes/images (images from jquery-ui-slider)
  * interface rewritten with JS/Backbone
  * to use, click Revisions: 'View' link, in post publish box
  * design cues from @karmatosed
 [http://core.trac.wordpress.org/attachment/ticket/23396/revisions9.png
 here] and @lessbloat [http://cl.ly/image/1u232c3Z3M0o here] (and developed
 in #23396)
  * revisions are loaded asynchronously
  * allows rapid review of all revisions using previous/next buttons and a
 slider
  * always shows what each revision contains - what it removed, added and
 what was unchanged, compared to the preceding revision
  * each diff is pre-calculated for rapid paging through revisions
  * allows comparison in split view or combined view, ajax refresh
  * allows user to show or hide (default) auto-saves, ajax refresh
  * skips revisions which include no changes, including the first save
 (note - unchanged revisions are no longer saved, see #7392)
  * includes link to old revisions system, for these missing features:
 revisions list, compare any two revisions and the easter egg :)

  the attached is a proof-of-concept, with plenty of room for improvement:
   * currently the diff view is not rendered until all revisions are loaded
   * diffs are calculated with each load, cache these calculations?
   * hook to turn off new revisions system for backwards compatibility,
 plugins
   * only load whats changes when options changed for auto-saves,
 split/combined view options ( currently refreshes revisions from server
 and logic is there )
