Val's Leaf Litter

Val's Leaf Litter provides a subtle tweak to the texture for the Leaf Litter block/item.

• Leaf Litter now has a more brown colormap.
• The individual leaves are not only more spaced out, but made sparse to make for more convincing tiling and to hide the "geometrical" nature of the blocks generation.
• The item texture for Leaf Litter is now unique.
