Deprecation issues

[jshin49]

There are two issues regarding deprecation, which prevents from upgrading to React 16

1. Warning: Accessing createClass via the main React package is deprecated, and will be removed in React v16.0. Use a plain JavaScript class instead. If you're not yet ready to migrate, create-react-class v15.* is available on npm as a temporary, drop-in replacement. For more info see https://fb.me/react-create-class

2. 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

This repository seems to be unmaintained, so I will fork it and create a PR, but in the meantime, you will be able to use the code from here

This is a common issue when upgrading to React 16+. The createClass and PropTypes were deprecated in React 16. Since this library appears to be unmaintained, you might want to consider using react-router's built-in scroll restoration or a modern alternative.
