Added env (IGNORE_OPEN) before openBrowser.

This env is chosen to make sure that there isn't a browser window showing up, when developing a Electron application. The start.js script can be used in the Electron index.js for launching the dev server and loading its url.

Hey! Thanks for the PR.

I think we won’t take it. I understand this is minimal, but we specifically don’t plan to tailor this tool for Electron apps. It would be frustrating if we merged this now, only to break something else later on.

I would encourage you to fork react-scripts provided by this package and publish react-electron-scripts or something like this, fine tuned to your use case.
