Tree Shade Variation (by JK)

Adds extra versions of most of the Temperate Climate trees and bushes. With ligher and darker variations and, for some, additional colour variations. Giving a much better non-uniform appearance to forests, up close and from a distance. If the mod is enabled when generating a Temperate map all trees will be used. If added to an existing saved game, these trees can only be added manually as assets. WARNING: If you remove this mod after trees have been placed with it, the game will still work, but they will replaced by whiteboxes as placeholders.
