#1081 addresses the Sound.Tidal.Boot changes and is ready for review. I've mostly got the handshake OSC changes ported too, but I want to add a couple tests and bug fixes to address #1030.

I'm also interested in taking a look at some of the package reorganization code, but can approach that more piecemeal.
