Ejection script

[skellock]

We don't need to have this read for 1.0... but

npm run eject?

It'll prompt you to replace parts of the app.

• package.json (author, build.appId, build.productName, build.publish, description, name, repository, version)
• readme.md
• docs sub-directory
• the irrelevant app parts like src/renderer/app/example-using-tabs and src/shared/models

For now, maybe we can just reference more of these things in here:
