Added Realism For Vehicles version 1.4.2.0 for Farming Simulator 2019 (v1.7.x)

The goal of this mod is to make the game more realistic by adjusting the real value of the vehicle.

Wheels:
In the base game, many vehicles do not take into account the tire type, for example,
the lizard pickup has unrealistically high friction on all types of terrain.
This mod fills in the missing data based on the tire track index, making it universal.
Different tire types now behave completely differently on various types of terrain and
wet differently from rain and sink into the ground.
This mod supports only 4 standard tire types: MUD, STREET, OFFROAD, and CRAWLERS!
- Calculates friction depending on tire size or width, tracks;
- Adds rolling resistance and lateral resistance;
- Higher load on the wheel, smaller tires, and soft ground = more force required for traction or pushing;
- Lower load on the wheel, larger tires, and hard ground = less effort needed for traction or pushing.

Transmission:
- This mod creates a simple automatic transmission for the vehicle based on minimum/maximum RPM and maximum allowable speed.
- The mod overwrites any gearratios in the XML!
- Changed the speedometer sensor from speed to engine RPM.
- Added clutch slip after gear shifts to provide smoother gear changes.

Implements:
- Traction force of "plows," "cultivators," and "seeders" – depends on the type of soil.
