Fix React.PropTypes deprecation warning

[eudaimos]

@jaredt67 thanks for making a thoughtful and useful package.

This PR was originally made to fix #3

Includes the following changes

• [x] install prop-types package as dependency per prop-types - How to depend on this package
• [x] change all instances of React.PropTypes to use from prop-types package - including in the example code
• [x] Updated peerDepency on react & react-dom to ^0.14.9 per prop-types - Compatibility
• [x] Added babel-cli as devDependency for building instead of relying on global install of babel-cli

Thanks for merging @jaredt67 - will you be publishing a release to NPM?

Thank you, @eudaimos! Yea, of course. So, the next version will be like 0.1.4 or 0.2.0?

@jaredt67 good question, I wouldn't consider a patch as it changes a dependency restriction although that change is a patch update - best to consult semver.org

I'm not sure if it's major or minor - but a few things 1) all pre-release versions (per semver) can make breaking changes so as you're below 1.0 you can pick either one - I think it's more than a patch 2) the package seems solid enough, I think you can bump to 1.0 (per doc updates #7 - I'll weigh in later today when I have some more time ) and make 2.0 the one with spinner support 3) please (per my request in #6 ) use Github releases to document your package versions - it'll not only help your users, but anyone trying to help support this package for you
