Hi,

We would like to use the eslint-3 channel but it is missing these plugins. Could they be added?

Thanks

@bobjflong sure thing. Made a PR: #165 and will plan to ship it later today.

Our process for adding plugins is written out here btw if you ever want to make a PR: https://github.com/codeclimate/codeclimate-eslint/blob/channel/eslint-3/CONTRIBUTING.md
