Title: 1765 handle twitter photos better

Using many twitter clients, images end up in the entities->media with the url and the image source,
such as the official twitter client. These photos are then replaced with a t.co short link
which is not easily/possibly expanded to the actual image url. But this data is available at
crawl time for us to grab and store properly in the links table.
