PropTypes has been moved in React v16

[carlost]

Starting with react v15.5 the use of React.PropTypes resulted in a deprecation warning. in v16 that module was moved to the prop-types package. This is causing react-native-bounceable to fail:

TypeErr: Cannot read property 'func' of undefined

React has scripts that can be used to update the source for this package: https://github.com/reactjs/react-codemod. although that is probably unnecessary because the change is pretty minor.
