Make accoridion work with more javascript frameworks

[hviid]

Some frameworks, like angularjs uses attributes on tags to do iteration of elements, see: ​http://docs.angularjs.org/#!/api/angular.widget.@ng:repeat

The Accordion iterates two elements <h3> and <div>, without them being wrapped in a parent, if this were changed the jQuery accordion could be used with 3rd party templating, which would be nice, since jQuery doesn't have any official templating atm.
