Twitter cards were not passing any useful metadata. A few things were being handled on Twitter's end by trying to match OpenGraph tags with their own, but it wasn't working at all for media. This is an attempt to fix that.
Common functions have been pulled out of opengraph and put into utils. Twitter's functionality was entirely replaced with a direct copy of Opengraph's and then modified as needed.
