alphabetize package.json

`npm install --save-dev` alphabetizes package.json, and I `ember init`
my app every ember-cli update and check the diffs, so this would be an
inconsistency.

Adds default description to addon

This change will provide a default description to all addons. This will help prevent addons with missing descriptions which is really commong for ember addons in npmjs.org and emberaddons.com. When a module has no description npmjs.org will try to use the README.md which contains markdown and looks like garbage on both npmjs.org and emberaddons.com.
