Recommended ESLint config for node.js (with babel)

This package contains an extensible shared config for nodejs apps written using babel.
It contains plugins:

• eslint-plugin-lodash - ESLint rules for lodash (underscore is forbidden)
• eslint-plugin-import - ESLint plugin with rules that help validate proper imports (require is forbidden)

It extends eslint-config-airbnb-base with a few changes (only the most important):
Added rules:

• no-restricted-syntax - loops (for, while) are not allowed (use lodash or bluebird for promises)
• complexity - max complexity is 20
• no-magic-numbers - disallow magic numbers, all numbers must be defined as constants (except: -1, 0, 1)
• callback-return - require return statements after callbacks
• handle-callback-err - require error handling in callbacks
• no-process-exit - disallow the use of process.exit() (some people use it for debugging)
• no-sync - disallow synchronous methods
• require-jsdoc - require JSDoc comments
• valid-jsdoc - enforce valid JSDoc comments (description for params and return is not required, types are required)
• max-len - max line length is 120, ignored for string and comments
• max-lines - max lines per file is 500
• max-nested-callbacks - max callback depth is 5
• max-params - max parameters in functions is 5
• max-statements - max statements in functions is 50

Removed rules:

• no-param-reassign - reassigning function parameters is enabled, it's useful in private methods
• no-plusplus - ++ and -- are allowed
