Made diesel render as brown in vehicle ui, fixing all resources

colours after gasoline, including water, fixes #9727
I think the "magic number" here in the vehicle interaction window was there to limit the number of fuel lines printed to only the four that fit in the space given. I'm not sure what this'll do if you somehow get 5 types of fuel (let's say, gasoline, batteries, clean water, hydrogen, and plutonium). Will it print onto the border of the veh_interact window?
