GP38-2 Sound Mod

Found the original sound files to be very lacking.
-Redesigned and layerd the engine sound files to create a more full sounding low end, and a rougher exhaust note.
-Fixed the ridiculously loud dyno sounds and added a cooling fan layer
-Changed the CSX and UP horn to a leslie 5 chime
The only thing required for each mod is the loco you wish to change the sound on

Shoutout to SpaceyKat for showing me the ropes and helping me through the process.
