v0.3.1

Docs-only release: the README is rewritten in plainer language, and the npm page now shows it. No code changes; the build is identical to 0.3.0.

v0.3.0

First release on npm: npm install react-grab react-grab-text.

• Measure is a full tool. The ruler in the React Grab toolbar shows an element's size, padding, and margins, and the distance to an anchored element.
• Everything runs on npm's react-grab@0.2.0. Text, Deck, and Measure attach to the stock toolbar, and CI tests each change against it and against the fork build.
• The script tag build is on unpkg: https://unpkg.com/react-grab-text@0.3.0/dist/global.global.js. It registers all three tools.

Installs pinned to the v0.2.0 git tag keep working.
