Cataclysm-dda: Recognize [ROAD] terrain at night

[Theundyingcode]

Is your feature request related to a problem? Please describe.
I am a big fan of rollerblades/roller skates but they are really difficult to use at night because you can't tell where the roads are. (tiles are all white or lt_green symbol on black background depending on whether night vision is in use and, roads share the same symbol as fields)

Describe the solution you'd like
Change the coloring so terrain with the [ROAD] flag has a dark grey background instead of a black one thus creating a visual distinction.

Describe alternatives you've considered
Change the symbols used to be distinguishable but that seems like a rabbit hole.

Additional context
I think that it is quite reasonable for a survivor to be able to distinguish between a road and a field even at night.

I don't use tilesets...

Another alternative would be for lane markers to be more easily visible than other terrain.

[CoroNaut]

Along with making lane markers more visible, perhaps we could introduce raised pavement markers that reflect light. If you shine a light that only goes 10 tiles, then the markers could light up to 20 tiles or so. If something is standing on a marker, don't light the marker. Also if something is between you and the marker, don't light all markers past it and you.
