Wave v0.5.2

A diagnostic build, plus the version fix underneath it.

The sidebar version was stuck at v0.1.0 because project.yml overrode
Info.plist. It reads correctly now.

Media debug logging goes to ~/Library/Logs/Wave/media.log, recording what
MediaRemote does at each step: loading the functions, registering, the isPlaying
check, and the result of sendCommand.

Registration moved from init to first use, so the run loop is ready by the
time it happens.

To help work out where pause is failing, play something, toggle recording once,
then read the log:

cat ~/Library/Logs/Wave/media.log

Open Wave.dmg and drag Wave into Applications, then relaunch it. This build
is signed ad hoc rather than with a Developer ID, so Gatekeeper refuses the
first launch: open System Settings, Privacy & Security, and the note about Wave
near the bottom has an Open Anyway button.
