Added a "configure-async-event-multicaster" attribute to the <message-bus/> element and a corresponding 'configureAsynEventMulticaster' property to the MessageBus class. When set to 'true', the 'taskScheduler' of the MessageBus will also be configured as the TaskExecutor for the ApplicationContext's ApplicationEventMulticaster. The default value for this property is 'false' (INT-58).
