Allows the event name and class name to be different

[demirmusa]

Implements IntegrationEventNameAttribute that allows the event name and class name to be different.

For example:

[IntegrationEventName("MyIntegrationEvent")]//you can change the name of the event
public class MyEvent : IntegrationEvent
{        
	///
}

May be required in cases where the event name conflicts with a class name in your project.
