Dev fixes

I was trying to get my dev instance of iNat back up and running today and cleaned a few things up in the process. Let me know if you'd prefer separate PRs.

Also, it looks like a lot of the specs are failing. Some of these are configuration issues (e.g my local copy are missing AWS and Flickr API keys), but others look to be real spec failures. Could you give me an idea of which of the specs are expected to be failing right now?
