text files are easier for humans to edit

The intent of this patch is two-fold:

1. Make it easier for humans to contribute. A line-delimited text file is easier to edit than a JSON file. People forget the commas!
1. Experiment with a build process like the one outlined by @isaacs in https://github.com/npm/docs.npmjs.com/issues/28#issuecomment-66803390. In this case it's `txt -> js` instead of `coffee -> js`, but the idea is the same: Use a combination of gitignore, npmignore, and npm scripts to create packages that can be enjoyed by humans and machines alike.
