React-confirm using really old react dependency

[vesakilp]

Used react dependency is really old, and leads to problems with shrinkwrap, basically it can't be used when using new react versions.

Yeah, I'm using it with React 16 and it works without issue (really great project, by the way, @haradakunihiko!). Should be a simple matter of incrementing the peerDependency to ^0.14.7 || 15.x || 16.x

Thanks for using react-confirm. I'd really like to modify and also update the example to use the latest React version, but currently have no time for this.
Could you kindly create a PR for this if possible?

Sent a quick PR that adds the peer dependency update, and changes the example in the README to use prop-types package (since PropTypes is no longer included in React).

I just saw that there are also a couple example apps, which I realize now is probably what you meant by "update the example", but I'm afraid I don't quite have time for that. FWIW, I don't believe anything else needs to change other than moving PropTypes and createClass (if used) into separate packages.

Thanks for the PR, your comment was helpful since I haven't used react for a while.
Merged and published. (Maybe I will release again once react@16 are published. )
