Also added a dedicated debugSound channel for debugging Fixes include closer conformance to original code (for entering/exiting ESPER and VK), and a change in assigning a track slot to a new track with priority equal to the lowest existing (it will now take the place of the old stored track). Also Music::adjustVolume() now takes the target volume as argument and stores it in the track volume field similar to how Music::adjustPan works.
