Maintenance release

• 0.1.3 - 2016-02-09: add argument drawSyndication call
  to support new retroactive posse feature in core.

Initial release

Adds some content types for IndieWeb-style like and repost. There are still some major outstanding issues:

• Conflicts with the Bookmark plugin. Both plugins claim the route /like/edit. In practice this means you cannot have both enabled at the same time.
• Reposts from Twitter pull in a bunch of html nonsense from Twitter's template.
