Create `eslint-config-react` package for react projects

[blurrah]

Based on https://github.com/labd/frontend-tooling/tree/master/packages/eslint-config but not horribly out of date.

Add it in and fix the babel parser: https://www.npmjs.com/package/@babel/eslint-parser

I have a PR ready for this: #4

[mhogeveen]

@blurrah @mitchellslager I believe this issue can be close due to #4 being merged, correct?

[mitchellslager]

@mhogeveen @blurrah I think so, but I can not close this issue myself.
