Delete Camo references & Addressable gem

At one point we piloted a "Camo" service to proxy HTTPS image urls for us, but it doesn't exist anymore.

We already have proxies and stuff for this, so I left `Image` as a placeholder for this, but it's not working yet!

This also deletes our final reference to the Addressable gem, so we can remove it!
