unicorn 1.1.0 - small changes and cleanups
This is a small, incremental feature release with some internal
changes to better support upcoming versions of the Rainbows! and
Zbatery web servers. There is no need to upgrade if you're
happy with 1.0.0, but also little danger in upgrading.
There is one pedantic bugfix which shouldn't affect anyone
and small documentation updates as well.
