Title: try to return a larger facebook photo when mapping

While the images array returned by facebook is mostly unhelpful (the images don't necessarily exist), @smurthas noticed that if a filename ends in _o (original), then it really exists at that size. This change checks for any images like that and returns them in our oembed as the canonical url.
