Add hubot.Robot.react

Per #360, this implements `robot.react` as a replacement for the
approach from:

https://github.com/mbland/hubot-slack-reaction-example/blob/v1.1.0/scripts/handle-reaction.coffee

Specifically, the `ReactionMessage` definition will no longer be
required in client code, and this:

  robot.listen(
    (message) -> message instanceof ReactionMessage
    handleReaction
  )

can now become:

  robot.react handleReaction

`robot.react` can also take optional  `matcher` and `options` arguments
just like the underlying `robot.listen` method:

  robot.react(
    (message) -> message.type == 'added' && message.reaction == '+1'
    {id: 'my-reaction-matcher'}
    handleReaction
  )
