        - test changes for <rdar://problem/5552943> accesskey does not focus <button> elements

        * fast/forms/access-key.html: Check for both focus and click events on all elements, but
        resisted the urge to switch to the American spelling for "focused".

        * fast/forms/access-key-expected.txt: Updated to reflect the bug fix ("1 button focussed"),
        the fact that <input type=button>, <input type=checkbox>, <input type=submit>, and
        <input type=reset> are all both focused and clicked ("2 input type button clicked",
        "3 input type checkbox clicked", "5 input type submit focussed", and
        "6 input type reset focussed"). Unfortunately this now also demonstrates that we don't
        send a click to <input type=text> and Gecko does. And there are still quite a few types
        that are not covered.
