[feature] Expose wait

[mousemke]

What needs to get done?

• the wait method from nightmare should be exposed.

Why does it need to get done?

before(function*() {
  yield niffy.goto('/', function*(nightmare) {
    yield nightmare.wait(3000);
  });
});

it seems odd that you would have to go through another call just to use wait through a callback. this exposes it to the niffy object

before(function*() {
  yield niffy.wait(3000);
});

How do I do it?

simply exposing it should do the trick

  /**
   * exposes the nightmare wait fubction
   *
   * @param {String} target selector of ms
   */
  * wait( target ){
      this.nightmare.wait( target );
    }
  }
