        Qt DRT: respect window.close() and window.closed()

        Qt DRT needs to maintain a correct count of open windows
        for windowCount(). It also needs to delete windows that
        have been closed by window.close().

        This fixes the following tests:

        plugins/destroy-during-npp-new.html
        fast/dom/Document/early-document-access.html
        fast/dom/Window/window-early-properties.html
        fast/events/open-window-from-another-frame.html
        fast/events/popup-blocking-click-in-iframe.html
