New features for the Dappled Forest

I have created a list of good features that I think fits for the new Dappled Forest biome:-

- Aster flowers: special flower variants that come in different colours, similar to tulips, and can be crafted into dyes. (Like purple Asters craft into purple dye, yellow Asters craft into yellow dye, etc.)

- Blueberries: a sweet berry variant that would grow only in Dappled forests and/or extreme hill biomes

- Brown bears: a bear variant that naturally lives in Dappled Forests. They can be hostile when a player goes near a baby bear cub. They can be tamed and bred with blueberries or raw salmon.

- Leaf Litter variants: Not colour dependent on the biome, but they come in three exclusive colour and pattern variants

- Larger shelf mushrooms could be collectable via Silk Touch, like Amethyst Clusters and Melons
