SwitchSound

This is a private method in NPCControl that aims to play the sound of turning on or off a wide variety of switch like objects. It receives a bool to indicate if the object is being actuated or deactuated.

Nothing happens if the startlife hasn't reached at least 15.0 frames.

In all cases, the Button sound is played on the entity with 1.0 volume, but the pitch depends on the actuation. If we are actuating, it's 1.0 pitch and 0.5 if we are deactuating.

There's a special case if the entity.originalid is the AncientPressurePlate, SwitchCrystal or BigCrystalSwitch animid. In that case another sound is played being a Glow sound using the same pitch variation as the other one, but the volume is the entity sound distance.
