remove duplicate keys from package.json
Use an addon to bring in ember-data.
Allow addons to preserve `main` entry point.

This allows packages to support both standard NPM usage (where the
`main` entry point is to the actual library) AND Ember CLI usage by
using the `ember-cli-addon-main` property if it is present.

Packages like `ic-ajax` and `emberfire` can use this to support both
types of consumers.
