This reverts commit 512915b7.

Also include babel-core bridge for Jest itself, which depends on Babel 6.

Required by update to babel-loader

Also requires updating babel-preset-react and babel-preset-env to @babel/preset-react and @babel/preset-env

Configure loaders so they operate on individual modules in scratch-*
dependencies.

scratch-gui exports `index.js` instead of just GUI container.

build in production mode on travis

Use absolute path when building library (production) so assets can be copied to /static in GUI consumer (like scratch-www)

- export image and sounds in dist/static/assets
- rename main export (`scratch-gui.js`, not `index.js`)
- move project-loader-hoc back to lib (VM doesn’t load properly without it)

export Library if `NODE_ENV===‘production’`, otherwise export playground and examples.

Allow intl to be passed in to GUI as a prop (rather than having to be already in the store)

Instead of using svg-url-loader only
