Add release date support (#14)

Closes #11 

Adds a couple of new utterances so you can limit your movie results by the release date. You can now add a movie by saying:

> Add The Godfather released in 1972
> Add The Godfather from 1972
> Add The Godfather that came out in 1972
> Add The Godfather released in March 1972

If you've used previous versions of the Intent Schema and Sample Utterances, make sure to copy and paste the new ones in.
