Audio channel states visible in debug view + some sound fixes:

Browse Source 
- a short "cooldown" after each footstep sound (prevents the sound playing multiple times during one footstep)
- water flow sounds are only played by one of the hulls a gap is between
- flow rate affects the range of the flow sound
