tools: move eslint from tools to tools/node_modules

This is required because we need to add the babel-eslint dependency
and it has to be able to resolve "eslint".
babel-eslint is required to support future ES features such as async
iterators and import.meta.

+cli-width
+=========
+
+Get stdout window width, with four fallbacks, `tty`, `output.columns`, a custom environment variable and then a default.
+
+[![npm version](https://badge.fury.io/js/cli-width.svg)](http://badge.fury.io/js/cli-width)
+[![Build Status](https://travis-ci.org/knownasilya/cli-width.svg)](https://travis-ci.org/knownasilya/cli-width)
+[![Coverage Status](https://coveralls.io/repos/knownasilya/cli-width/badge.svg?branch=master&service=github)](https://coveralls.io/github/knownasilya/cli-width?branch=master)
+
+## Usage
+
+```
+npm install --save cli-width
+```
+
+```js
+'use strict';
+
+var cliWidth = require('cli-width');
+
+cliWidth(); // maybe 204 :)
+```
+
+You can also set the `CLI_WIDTH` environment variable.
+
+If none of the methods are supported, and the environment variable isn't set,
+the default width value is going to be `0`, that can be changed using the configurable `options`.
+
+## API
+
+### cliWidth([options])
+
+`cliWidth` can be configured using an `options` parameter, the possible properties are:
+
+- **defaultWidth**\<number\> Defines a default value to be used if none of the methods are available, defaults to `0`
+- **output**\<object\> A stream to be used to read width values from, defaults to `process.stdout`
+- **tty**\<object\> TTY module to try to read width from as a fallback, defaults to `require('tty')`
+
+
+### Examples
+
+Defining both a default width value and a stream output to try to read from:
+
+```js
+var cliWidth = require('cli-width');
+var ttys = require('ttys');
+
+cliWidth({
+  defaultWidth: 80,
+  output: ttys.output
+});
+```
+
+Defines a different tty module to read width from:
+
+```js
+var cliWidth = require('cli-width');
+var ttys = require('ttys');
+
+cliWidth({
+  tty: ttys
+});
+```
+
+## Tests
+
+```bash
+npm install
+npm test
+```
+
+Coverage can be generated with `npm run coverage`.
