Dev

Currently, rake passes, but only because I pulled out the steps where I test that I can see someone else's picture. I am unable to successfully save changes to a user in the rails console with an empty github key and I cannot figure out how to create additional users in the development environment using the github authentication. As a result I am not able to thoroughly test this feature, but I did not want to keep you waiting for the pull request.
