Fires whenever a benefit is fulfilled by a GameWisp channel
Using Socket.IO this benefit can be listened to as follows:
socket.on('benefit-fulfilled', function(data){
//Do something.
});
This event fires when a channel fulfills a benefit. The structure of the response is similar to the subscriber-benefits-change except that the benefits array only contains the benefit-fulfillment pair of the fulfilled benefit.
This event only fires for benefits that the channel fulfills manually through the GameWisp channel dashboard.
