Show images of vehicles in the window of scenario info and pop-up windows.

[Yona-TYT]

Well, I'm still working on the tutorial scenario, now I want to show more clearly the vehicle that the tutorial wants the player to use.

For example: if the player chooses the wrong vehicle, an image will appear suggesting the correct vehicle.

It would be something like: vehicle_x.get_imange ()

It should not be something very difficult to add, since in "message center" this is already possible (although there is an error there).

I would like to improve the tutorial with this, greetings!
