Title: ensure NODE_ENV is valid and default regex for walk

- Move NODE_ENV determination into `config.js` and make sure it is valid. Otherwise, default to `development`.
- Set `/(.*)\.(js|coffee)$/` as the default regex for walk utility, as this is the most prevalent case. Centralizing adheres to DRY and reduces possibility of copy/paste error.
