Feature: add constants to add more meaning to magic numbers

[CrosRoad95]

Is your feature request related to a problem? Please describe.

for example: setVehicleLightState( car, 0, 1 ) do you know what it does? assume that without taking look at wiki you wont know.

Describe the solution you'd like

add meaning to this numbers, it would be more readable if it would be written in form: setVehicleLightState( car, VehicleLight.FrontLeft, VehicleLightState.Broken)

Describe alternatives you've considered

/

Additional context

it could be added simillar to how inspect function is created, create file "constants.lua" and put there code:

VehicleLight = {
  FrontLeft = 0,
  FrontRight = 1,
  RearRight = 2,
  RearLeft = 3,
}

this solution if fully backwards compatible, people over time can migrate their code to use constants
