        Turning off plugins causes crash

        When an active page has plug-ins, and plug-ins are disabled, they will be stopped and will
        end up in a state where they don't have an event handler. Because of this, we need to
        check that the plug-in has been started before calling the event handler.

        * Plugins/WebBaseNetscapePluginView.mm:
        (-[WebBaseNetscapePluginView sendActivateEvent:]):
        (-[WebBaseNetscapePluginView sendDrawRectEvent:]):
