Add per-node scene music volume control

Browse Source 
Author a music track and volume (0-100%) per story node; the runtime
scales it to 0-1 and applies it without restarting the track when only
the level changes. Adds migration 024, threads music_volume through the
repository/runtime, and gives the node inspector a volume slider.
