Support other eslint config types


ESLint supports a variety of config types.

I am using .eslintrc.js for a project, and it would be nice for Cloud9 to use the same file.


Support for even a regular .eslintrc file would be nice, I (+ a bunch of other people, judging from the forum search results) have had issues with the GUI not showing customized eslint errors.


The default linter in Cloud9 IDE uses a browser copy of eslint that does not support all of the same features as the cli tool, I wrote this plugin to fix the issues I had been having personally and it supports eslint properly like if you were using the eslint cli including all of the file formats.
