jQuery ESLint config

Usage

``sh
npm install --save-dev eslint-config-jquery
`

Configure ESLint with a .eslintrc file using the following contents:
`json
{
"extends": "jquery"
}
``

Status

This config follows the spirit of the jQuery code style, does not violate it and extends it.

Semver policy

Same approach as in ESLint, see https://github.com/eslint/eslint#user-content-semantic-versioning-policy.
