Set the max Hubot version to 2.14.0.

In version 2.14.0, Hubot started using the `async` module for responding to received messages (in `Hubot.Robot`).  Tests can technically still be run with the current code, but all tests will need to be modified to include a short timeout in the `beforeEach` function.

```coffeescript
    beforeEach (done) ->
      room.user.say 'alice', 'hubot pug me'
      setTimeout done, 50
```
