Add Badges to the app.

The app syncs with an instance of openbadger, and then presents the badges in the app. For testing purposes, you can add these bits to your config to test. It will load badges from an instance of openbadger we set up for connected educators month:
```
    "obrEndpoint": "http://badger.connectededucators.org/v2",
    "obrProgram": "connected-educator-month-start-kit"
```
This adds two views,

We're working on styling the above, but might need a hand with it. @iamjessklein and @chloeatplay are working on styling. I'll do my best to implement their design, but am not so awesome at front-end styling. Here's the badge listing view for badges.openbadges.org, which we'll use as a template (though it will fit in a single column).
