SCS Livestock Trailer Rework v1.0 - 1.44/1.45

This mod is a fix for the ridiculous bad dimensions of the original livestock trailer. As you may know, the original trailer is very tall and narrow, wich makes it look innacurate. Also, the tandem axle chassis option in the ownable version looks bad, because it has the same length than the tri axle and spread axle chassis.
