This diff switches sysutils/tray-app to the new audio control API. Now
the programm displays and controls the sndiod master volume knob. This
has two advantages:
- tray-app now works on any device, including those with no volume
controls.
- in case there are multiple audio devices, tray-app won't pick the
wrong one anymore
OK?
