Better Biome Variation on Maps

Maps should be reworked to make different biomes more distinct from each other. The issue lies in the grass blocks being the exact same colour across the entire map, rather than matching the biome colour.

For instance, a map should display the grass in a spruce forest as dark green and a jungle as  vibrant green. Instead, maps of land with plenty of biome diversity are reduced to the same default green grass and you can hardly tell the difference between a jungle or savannah.

Currently, this makes mapping out a large section of land boring by knowing that the map is going to look plain. But a much needed fix could get players excitedly running around their home continent to have a grand map on display in their base.
