Track list export

The initial track list was exported with this quick code, which can be run as a C# mod:

source code

    }
}

public class SoundInfo
{
    public string Category { get; set; }
    public string Name { get; set; }
    public int Id { get; set; }
}

The game data only has the numerical category IDs, but I confirmed the category names with one of the game developers:

id	name	my notes
1	`Default`	seems to be unused.
2	`Music`
3	`Sound`
4	`Ambient`	listed on the wiki as "Music (ambient)" just to group the music tracks.
5	`Footsteps`
