Moved "eslint-env node" to the root

It seem's kind of pointless setting the comment "/* eslint-env node */" at the top of only some JavaScript files when nearly all of them are Node.js releated, so I moved this option to the root level config, only leaving the 'lib' folder as "/* eslint-env commonjs */"
