Version 1.16

Since 1.13, a lot has changed. Not really, just kidding, but a few
things have. Basically, nowadays, Instapaper and Pocket etc will parse
the post title instead of the blog title (that's a bug-fix, folks) and
there are 11 more social services available than there were before. It
used to be 30. Now it's 41. Math.

I don't know, there were probably more things since then, but now that
Tumblr pushes updates automatically, I'm being admittedly less diligent
about enumerating changes in the repo.
