tools: update ESLint to 4.2.0

ESLint 4.2.0 contains a fix for a bug that is blocking us from moving to
the non-legacy stricter indentation linting. Update to 4.2.0 to remove
the blocking issue.

-# generate-function
-
-Module that helps you write generated functions in Node
-
-```
-npm install generate-function
-```
-
-[![build status](http://img.shields.io/travis/mafintosh/generate-function.svg?style=flat)](http://travis-ci.org/mafintosh/generate-function)
-
-## Disclamer
-
-Writing code that generates code is hard.
-You should only use this if you really, really, really need this for performance reasons (like schema validators / parsers etc).
-
-## Usage
-
-``` js
-var genfun = require('generate-function')
-
-var addNumber = function(val) {
-  var fn = genfun()
-    ('function add(n) {')
-      ('return n + %d', val) // supports format strings to insert values
-    ('}')
-
-  return fn.toFunction() // will compile the function
-}
-
-var add2 = addNumber(2)
-
-console.log('1+2=', add2(1))
-console.log(add2.toString()) // prints the generated function
-```
-
-If you need to close over variables in your generated function pass them to `toFunction(scope)`
-
-``` js
-var multiply = function(a, b) {
-  return a * b
-}
-
-var addAndMultiplyNumber = function(val) {
-  var fn = genfun()
-    ('function(n) {')
-      ('if (typeof n !== "number") {') // ending a line with { will indent the source
-        ('throw new Error("argument should be a number")')
-      ('}')
-      ('var result = multiply(%d, n+%d)', val, val)
-      ('return result')
-    ('}')
-
-  // use fn.toString() if you want to see the generated source
-
-  return fn.toFunction({
-    multiply: multiply
-  })
-}
-
-var addAndMultiply2 = addAndMultiplyNumber(2)
-
-console.log('(3 + 2) * 2 =', addAndMultiply2(3))
-```
