International 9400i Eagle Truck 1.31

I decided to give life to a mod that was mostly unknown to most of you.

Here’s a small changelog :

-updated pmg files (most of them)

-fixed air and oil gauge errors

-Compatible for 1.31, but should work for 1.30 for those not in public beta

Works on latest version with a couple of errors in the log (shouldn’t crash the game)
