Version 2.0.0

• Release date: 27 March 2013;
• Thanks to @nfreear for adding tests and HTML4 element support.
  Really a great extension.
• The jQuery version is now deprecated.
• The CDN version got updated, the jQuery version was replaced by the non-jQuery version.
  (They share the same API, so there shouldn’t be a problem here.)

Version 1.5

• Release date: Feb 19, 2013;
• Added support for the standard element as specified by the W3C.
  If you specify your own element for the main role,
  I reset the main role for the element.
  (There can’t be more than one element with the role main.)
