Real Company Mod v2.0 for American Truck Simulator game.

Features:
Changed some company names and logos to real ones;
(All the companies in the future)
After some research I find the ideal substitute company
in order to have all the cargo making sense;
Also changed the respective trailer skins to the new ones:

Company list:
Walbert -----------> Walmart
Plaster & Sons ----> Centex
