Adds massive cargo ships to the game, that function similarly to trains. Also adds deep sea oil, oil platforms, tanker ships, train bridges and other water based content.
Found a small bug that only came up after last update (I think), when equipping a water-based items, the reach expands as expected, however doesn't reset to the normal reach when swapping to another item (doesn't matter if you clear with 'q' or direct switch). Player death resets reach but stays long again the next time you pick up a water-based item.
