Migrate to PropTypes from React.PropTypes

[justinchen]

React 16 moved PropTypes to a standalone library. This commit adds the package and changes calls to React.PropTypes to PropTypes.

Thanks @justinchen - Have you tested that the demo site still works, or does that need a PR also?

@freeranger I just confirmed the demo works once you add the prop-types package.

Thanks @justinchen.
I just tried to npm install locally so I can test out the change and I am getting:
ReferenceError: Unknown plugin "'transform-es2015-modules-umd'" specified in "base" at 0, attempted to resolve relative to "src"
I don't know if this is related to your change or something in babel - I will have to investigate further.
What version of babel did you end up with when you did npm install?

@freeranger It grabbed 6.26.0 for me.

@justinchen ok thanks. I was using an unfamiliar machine - I will try again at the weekend from my regular dev box..

Thanks @justinchen - all merged in now.
