Remove the include setting from webpack loaders for CSS, JSON and other static assets.
This way it's possible to import files from a separate config folder, a parent directory etc.
Fixes #497 (closed).
Test plan:
Created a test-config.json with contents {} in the root folder of create-react-app and added import '../../test-config.json'; to template/src/App.js. The app started and was built successfully.
