Across the entire audio system, audio now works in 0-1 terms instead of 0-100 as before. Therefore, volume is now a double instead of an int. The master volume of the AudioServer changes smoothly through a FadingProperty, preventing clicks. Finally, volume computations are done with logarithmic scaling, which is more natural for the human ear. Note that this could be 4-5 different commits, but as they change each other's code all the time, it makes no sense to split them up.
