Add a config subdir to project and hot config reloading so config dir is able to be mounted and updated from a centralized source

Would be cool if you supported multiple config backends like https://github.com/micro/go-config

This works currently, config.js's are expected to export an object; you can import whatever config medium you like here so long as it exports an object:

An example:

module.exports = ini.parse('./config.ini');
