Valentin Shergin d49ebbcf62 Fabric: All *EventHandlers were renamed to *EventEmitter
Summary:
Using `EventHandlers` name was a bad idea, and I cannot tolerate it anymore.
The worst part of it is that when you have a collection of `EventHandlers` objects you cannot use plural word to describe it because `EventHandlers` is an already plural word.

And, this object is actually an event emitter, the thing on which we call events.
