react-syntax-highlighter 13.5.0

on Node.js NPM

Enhancements

• #299: clean up old files in project root, add jest to eslint

Grateful to @ktmud for stepping in with that improvement.

Dependency updates

• #300: Updated to refractor 3.1.0, which brings in prismjs 1.21.0. We'd pinned react-syntax-highlighter 13.3.1 to prismjs 1.21.0, but didn't realize that refractor's dependency would keep us at 1.20.0
