Deprecated use of PropTypes validation function

[iest]

Manually calling PropTypes validators has been deprecated in React 15.3.0, showing the following warning:

Warning: You are manually calling a React.PropTypes validation function for the tagName prop on ComponentName. This is deprecated and will not work in the next major version. You may be seeing this warning due to a third-party PropTypes library. See https://fb.me/react-warning-dont-call-proptypes for details.

This would be solved by upgrading react-prop-types to 0.4.0
