Create-react-app: Move launch-editor logic to react-error-overlay

[HaNdTriX]

Request

It would be awesome if we could move all react-error-overlay logic into the react-error-overlay package.

Reason

Currently it is not possible to use all features react-error-overlay without installing react-dev-utils.

Files that should be migrated:

• react-dev-utils/errorOverlayMiddleware.js
• react-dev-utils/launchEditor.js
• react-dev-utils/launchEditorEndpoint.js

 Alternative

Solved by https://github.com/yyx990803/launch-editor/

As an alternative it would also make sense to move the react-dev-utils/launchEditor.js into its own package. The electron community might appreciate it.

Since there is already an open-editor package on npm this would be a great place. (https://github.com/sindresorhus/open-editor/issues/4)

There's already a published standalone package (with webpack middleware available):
