2.0 plugin revamp

[chrisblossom]

Additional v2 Information
README.md

Changes:

• No configuration is needed for standard usage (cleans webpack's output.path)
• By default during webpack's watch mode, only files created by webpack are removed
• Because del is used, globbing is supported
• Plugin is tested directly via webpack
• All supported versions are tested
• Windows is tested via appveyor (no mocked tests)
• Complete build system including prepublish hooks and git prepush/commit hooks
• Written with Typescript

Additional notes:

• Moved to CircleCI because Travis CI was sold and looks to now be in maintenance mode.
• Replaced Coveralls with codecov because automatic build merging works. This is important because of windows/different webpack version testing

Please discuss the current API and suggest any changes.

This looks great! Thank you for putting in the work on this @chrisblossom 🎉
Should we merge this into master and push to npm?

[chrisblossom]

Yes I think we should. Should I change the version from 2.0.0-alpha1 to 2.0.0?

Also, I'll need you to sign up and add to the github repo circleci.com, appveyor and codecov.io. Let me know if you use a different username than johnagan for any of the services so I can update the readme links.

I think this should all be done before publishing to NPM.

[johnagan]

add to the github repo circleci.com, appveyor and codecov.io.

Thanks for getting that done!

With CircleCI, you'll want to turn on Settings > Build Settings > Advanced Settings > Build forked pull requests.

Do you want to release a @next 2.0.0-alpha1 version or go straight into 2.0.0? I think releasing this as 2.0.0 will get the most/quickest feedback and since del's force option is disabled by default, it will not remove any files outside of a project. Also their webpack config will throw an error because the API has completely changed.

done!

Let's go with 2.0.0 and see how it goes

[chrisblossom]

Can you add me to the AppVeyor team? My username is chrisblossom, email cbloss@gmail.com. I just want to be able to re-run builds.

Looks like CircleCI already lets me because I'm a github collaborator for this repo. If you want help maintaining the npm version, my npm username is chrisblossom.

I'm going to go ahead and merge this in. Once you push to NPM, I'll close the issues/PRs I linked in this PR.

Wow, that's amazing. Phenomenal!
