Easy Change Transmission Type

This script allows you to change the transmission type (except from vehicles with a CVT transmission) directly via keyboard input.
This changes the global setting "Gear Shift Mode" in the settings page.
By default, setting the gear shift mode to "Automatic" would cause
all vehicles to be shifted automatically, including vehicles that are shifted manually in real life. With this script, you can switch through the modes "Automatic" and "Manual" / "Manual + Clutch" ,
without having to switch to the settings page every time. Once you've set a transmission type for a vehicle, it gets saved and if you enter the vehicle again, this type is being activated automatically.
Default assignment:
Switch transmission type: "DEL"
Transmission type automatic: not assigned
Transmission type manual: not assigned
Transmission type manual + clutch: not assigned
CHANGELOG 1.1.0.0:
- Transmission type gets now saved for every vehicle
