visual studio code eslint support

Created by: tzapu

Description

The docs here https://github.com/facebookincubator/create-react-app/blob/master/packages/react-scripts/template/README.md mention that vs code should support the eslint config without doing anything extra

VS Code ESLint plugin automatically detects Create React App's configuration file. So you do not need to create eslintrc.json at the root directory, except when you want to add your own rules. In that case, you should include CRA's config by adding this line:

in practice, with latest versions of everything, i still had to add .eslintrc containing { "extends": "react-app" } in order for the editor to load a config

Expected behavior

VS Code ESLint plugin automatically detects Create React App's configuration file

Actual behavior

VS Code ESLint plugin needs and .eslintrc file to detect any config

Environment

Run these commands in the project folder and fill in their results:

npm ls react-scripts └── react-scripts@0.9.5 node -v v7.8.0 npm -v 4.2.0

Operating system: macOS

I am not sure if this is a bug or a lack in documentation or I m just doing something wrong. If it's the docs i can make a pull request I guess Cheers
