Support replyAndUpdate

[Erik Kristensen]

It would be great if this mock library could also support the replyAndUpdate function from botkit.

Thanks for the library!

@ekristen we'll add this functionality to projects (https://github.com/gratifyguy/botkit-mock/projects) and see if we can get someone to help us support replyAndUpdate.

Feel free to submit a PR patching replyAndUpdate support if you write it first!

@ekristen already merged #35 + published to npm 0.1.3
