Multiple Trailers in Traffic - ATS - v7.1

Changelog v7.1
Trucks and trailers already included by SCS are no longer in the base mod.
International Lonestars with both "A" and "B" cabs for regular double/triple trailers, heavy cargo and forestry trailers.
Single/triple versions of the doubles in Jazzycat's Painted Truck traffic mod. Use v3.9.1 or later to avoid warnings during loading.
Standalone mod to allow Rocky Mountain/Turnpike double and pup triple trailers for cargo in states and provinces in CanaDream, C2C and the various Mexico maps.
More truck templates.

v7.1:
Adds: Mack Anthems.
Removes: Far too many stupid errors; no-longer-required cargo models "borrowed" from ETS2.
Changes: All truck models now in Heavy & Forestry Addons; further tweaks to spawn ratios/frequencies.
Resurrects: The Case 600 Quadtrac tractor in the Heavy Addon, which SCS had just hidden rather than removed altogether.
