Notable changes

• Twitter:
  • Handle new "extended" tweets with hidden reply-to @-mentions and trailing URLs for media, quote tweets, etc. Background: https://dev.twitter.com/overview/api/upcoming-changes-to-tweets
  • Bug fix: ensure like.author.displayName is a plain unicode string so that it can be pickled normally, e.g. by App Engine's memcache.
  • Bug fix: handle names with emoji correctly in favorites_html_to_likes().
  • Bug fix: handle search queries with unicode characters.
• Atom:
  • Render full original quoted tweet in retweets of quote tweets.
• microformats2 HTML:
  • Optionally follow and fetch rel="author" links.
  • Improve mapping between microformats2 and ActivityStreams 'photo' types. (mf2 'photo' type is a note or article with a photo, but AS 'photo' type is a photo. So, map mf2 photos to underlying type without photo.)
  • Support location properties beyond h-card, e.g. h-adr, h-geo, u-geo, and even when properties like latitude and longitude appear at the top level.
• Error handling: return HTTP 502 for non-JSON API responses, 504 for connection failures.
