Add base routes for source files

[selbekk]

In order to avoid stuff like this:

import SomeComponent from '../../component/some-component/SomeComponent';

, I usually use the babel-root-plugin to resolve ~ to /src/main.

Would the suggested way of doing this in CRA be to fork and change react-scripts? Or is there a way to do this already?
