[UI] - Color code runaway association

:bullseye: What is your suggestion?
On airports with multiple runaways, once plane is associated with particular runaway (scheduled or assigned), color code its card in the list.

:hammer_and_wrench: How would it work in the game?
When player schedule a stand for an airplane, plane will have to use specific runaway. When such association exists (either by using scheduling, or associating plane to a stand - which takes precedence), add a color to plane card.

Color is removed when plane lands.

Same can be applied to departing planes, with different or same color, depending on runaway used for departing.

:balance_scale: Why is this a good idea?
Managing airports with multiple runaways is quite difficult and with just one list with all planes in it, it become messy sooner or later.

This should help in organization and better usage of runaways.

It will also make more room for enjoying a smooth operations on an airport, even on a bigger airports.

This is an example of IAD arrivals.
Green cards - use 19L
Blue cards - use 19C
Pink cards - 19R
Cards without color are not scheduled nor assigned to a stand.

Totally agree with this feature

Very cool idea
