#3917
* moved format location into separate file
allow dependencies to report errors too
* NullDependencies do not change the hash
* dependencies can opt-out from `__webpack_require__` param
* apply module syntax plugins earlier
* emit errors if using AMD or CommonJS syntax in harmony modules
* refactor(eslint): Added no-unsed-vars, env specific .eslintrc's for buildin & hot
* This change allows for buildin to now be part of the lint test by addition of an extra .eslintrc file which extends existing but sets es6 to false
* Turned on no-unused-vars for eslint, and then removed all warnings from turning that feature on
* Was getting notified of errors in "quote" property in eslintrc, so changed to correct value from error to 2.
* beautify
* swap invalid eslint config val
