        Eliminate the notion of "temporary events"

        We mark some events as temporary when dispatching, for the sole reason of
        manually calling forgetDOMObject when done dispatching.

        There doesn't seem to be any reason to call it manually, as JSEvent destructor
        will do this automatically right away.

        * bindings/js/ScriptController.cpp:
        * bindings/js/ScriptController.h:
        Removed ScriptController::finishedWithEvent(), which was called after dispatching
        a temporary event.
