#544418 by merlinofchaos, sun, drewish, quicksketch, et al: Integrate CTools AJAX framework with Drupal to extend (and replace) existing ahah framework. Everything about AJAX/AHAH is more betterer now.

    * that the Recent Poll block outputs the block layout rather than page layout.
    * that users can vote on polls via the block
    * that the 'older polls' link in the recent poll block works.
    * that node is output correctly, including 'Cancel your vote' button appearing
    * that only users with appropriate permission can cancel their votes
    * that the 'poll' page contains the correct data.
    * that polls can be edited
    * the opening / closing of polls - ensuring block doesn't appear when poll is closed, and neither do the 'Vote' / 'Cancel your vote' buttons, and that the poll status is updated correctly on 'poll' page.

  Drupal core!  This is an important milestone for the project so enable
  the module and check it out ... :)

  Thanks to Rok Žlender, Károly Négyesi, Jimmy Berry, Kevin Bridges, Charlie
  Gordon, Douglas Hubler, Miglius Alaburda, Andy Kirkham, Dimitri13, Kieran
  Lal, Moshe Weitzman, and the many other people that helped with testing
  over the past years and that drove this home.

  It all works but it is still rough around the edges (i.e. documentation
  is still being written, the coding style is not 100% yet, a number of
  tests still fail) but we spent the entire weekend working on it in Paris
  and made a ton of progress.  The best way to help and to get up to speed,
  is to start writing and contributing some tests ... as well as fixing
  some of the failures.

  For those willing to help with improving the test framework, here are
  some next steps and issues to resolve:

    - How to best approach unit tests and mock functions?
    - How to test drupal_mail() and drupal_http_request()?
    - How to improve the admin UI so we have a nice progress bar?
    - How best to do code coverage?
