Consider adding responds(type) method

See original GitHub issue

Would you consider adding such a method that allows to check if the emitter responds to a given event?

EventEmitter.prototype.responds = function(type) {
  return !!(this._all || this._events && this._events[type]);

I’m happy to create a PR if this is of use.

I think it would have to be isListeningTo(event) then. But how abouthasListeners([type])? That would work both with and without the type argument.

Thanks @DigitalBrainJS for taking care of this, and apologies for being slow (swamped with work currently…)
