        Fixes http://bugzilla.opendarwin.org/show_bug.cgi?id=10953
        Test results for fast/js/window-properties.html should include
        children of window.document.body.firstChild

        * fast/js/window-properties-expected.txt: Regenerate results which now
        include window.document.body.firstChild.*
        * fast/js/window-properties.html: Print out 'null' for null objects
        instead of 'object' for more clarity
