        Added close methods that need to be called before these
        objects can be released. This ensures proper tear-down under GC.

        <rdar://problem/4484405> WebKit leaks, improper tear-down

        Adds a close method to WebView, this needs to be called when the 
        WebView is no longer needed. To make this easier for the common cases
        there is now an "auto close" on WebView that listens to the view's
        parent window. If the parent window closes and the WebView has no
        hostWindow then the WebView is automatically closed if autoClose is YES.
        To manage WebView closing yourself call setAutoClose: and pass NO.

        When a WebView closes it will tear-down and not be usable anymore.
        Close will will called on various other internal objects as a part
        of this, to ensure proper tear-down in GC without relying on finalize.

        Need to call window close so WebView tears-down completly.

        * DumpRenderTree/DumpRenderTree.m:
        (main): call [window close]
