v4.0.0

Added

• Support for ArchieML files. These are processed when they are found with the .aml extension.
• Support for JavaScript files. This includes any JavaScript file that provides a default export (module.exports = ...). JavaScript files that export functions, including async functions, are also supported! This makes it possible for quaff to load data that's fetched from an API. Load GraphQL and go to town! Do some extra-preprocessing!

Changed

• quaff now returns a Promise to enable async resolution of JavaScript files.
• Moves testing to nyc.
• Now requires Node.js 8 or later.
