Kenworth W900 engine sound 1.37

Just a test version of mod. Looks like it is impossible to do good interior sound with SCS filters, it will be better if SCS create event for interior sound separate without filters for exterior sound.
And I can solve how to do engine stop sound when RPM drop too fast than I create sound volume curve on "timeline" tab.

Audio settings was reset to default when mod created.
SOunds like blinkers, wipers and so on remain the same.
