Update webpack to version 2.3.0 🚀

[greenkeeperio-bot]

Hello lovely humans,

webpack just published its new version 2.3.0.

State	Update 🚀
Dependency	webpack
New version	2.3.0
Type	devDependency

This version is not covered by your current version range.

Without accepting this pull request your project will work just like it did before. There might be a bunch of new features, fixes and perf improvements that the maintainers worked on for you though.

I recommend you look into these changes and try to get onto the latest version of webpack.
Given that you have a decent test suite, a passing build is a strong indicator that you can take advantage of these changes by merging the proposed change into your project. Otherwise this branch is a great starting point for you to work on the update.

Do you have any ideas how I could improve these pull requests? Did I report anything you think isn’t right?
Are you unsure about how things are supposed to work?

There is a collection of frequently asked questions and while I’m just a bot, there is a group of people who are happy to teach me new things. Let them know.

Good luck with your project ✨

You rock!

GitHub Release

Features:

• add extensions option to DllReferencePlugin

• add extractComments to UglifyJsPlugin to move kept comments into separate file (i. e. LICENSE file)
• validate relative and absolute paths in configuration
• validate stats options
• allow to match on compiler (name in configuration) in rules
  • i. e. allows to specify different rules for extract-text-webpack-plugin or html-webpack-plugin
• Allow to pass multiple entries via CLI
• Performance improvements
• CommonsChunkPlugin give errors on incorrect options
• add module.strictExportPresence to make missing export an error instead of warning
• Compiler emits watch-close event when the watcher is closed

Bugfixes:

• Watcher now detects file deleting correctly
• Resolve output path if relative output path is given via CLI
• Handle stack traces in errors correctly
• Some usages of System now generate valid code i. e. System.global
