This is the dramatic refactor which was alluded to in ed004e0.
1. All output goes through a central module.
2. Callbacks are called when data is flushed, but only ever called once
3. Set "outfd" and "logfd" to direct output and error to different places,
or set to a writable stream when using npm programmatically.
4. Clean up the many varied ways to write data to the console.
5. Set colors smarter, and allow overriding by setting the "color" config.
