Fix multiple callback calls

• add global callback to help you set all listeners and interceptors using just one method. Use addCallback(callback).
• fix: call interceptActionFire with action which it was added with.
• fix bug when listeners was called more than once if the same instance of action was added few times in different CompositeActions or DialogWrappers.
