Add pre-publishing script and bump version to 2.0.0-rc1 (#494)

* Add a `prepack` script to run before publish

This will re-install dependencies, run linting on PHP, CSS, and JS, run the JS tests, and lastly build the production bundle.

* phpcs is now part of `npm run lint` so we don’t need to run it twice

* Version bump to RC1
