extra `emitter` methods to use with `.withHandler` and `.fromBinder` about kefir

[rpominov]

Yep, something like .emitEvent in emitter object makes sense. As well as in emitter stream, at least for consistency. Will add it soon.

How about .plug? (It does seem like Event and Pool and Bus might all bleed together a bit, though I understand they are technically different concepts.)

Not sure about this, not very easy to add, and will probably make .withHandler (and other methods where emitter object are used) a bit heavier.

You can use .flatMap for this. And, if you need to handle all kind of events, something like this:

stream.withHandler(function(event, emitter) {
  emitter.emit(event); // emitting event object as value, so all events available in next step
}).flatMap(function(event) { ... })
