Added Ambarlı, the big container port on Istanbul's Marmara coast. It's a row of long piers running out into the harbor, each one packed with docks.
There's plenty of docking space, but the lanes between the piers are narrow, so getting big ships in and out without a jam takes some planning.
Container colors are now fully customizable in the settings menu. Every container color can be set to whatever color you want, and the harbor structures (walls and inner area) can be recolored too.
