Warning: Accessing PropTypes via the main React package is deprecated

[andrewhl]

I get the following warning from React v16.0.

Warning: Accessing PropTypes via the main React package is deprecated, and will be removed in React v16.0. Use the latest available v15.* prop-types package from npm instead. For info on usage, compatibility, migration and more, see https://fb.me/prop-types-docs

react-tinymce/lib/components/TinyMCE.js

Lines 35 to 40 in a25b204

	propTypes: {
	config: React.PropTypes.object,
	content: React.PropTypes.string,
	id: React.PropTypes.string,
	className: React.PropTypes.string,
	name: React.PropTypes.string

I can submit a PR to clean this up if you'd like.
