Route Based TTrack Sounds

[peternewell]

This PR adds the ability to define track based sounds "within" the route, and thus removes need for individual stock to have track sounds associated with it.

Hi Peter,

I was wondering what happens when a route-based sound and a traincar-based sound are both valid? Do we hear them both or does one take precedence? What is the mechanism to choose the precedence?

Best wishes,

Chris

If there are track based sounds in the car then they will be heard.

I am unaware of how to disable car based track sounds as I don't believe that they have a specific trigger that could be "ignored"?

Hence it will probably require Users to remove track based sounds from the cars SMS file.
