made plants show up again

fixed some material wang collisions and a small error spam

made plants and mycelium corpses even more box2d like

new fake box2d is now pixel perfect!

supposedly addressed from error spam

burnable, consumable, diggable, splittable plants and mycelium while having NO collisions with box2d objects, projectiles or player. Contributing to the title of Purely Aesthetic!

slightly better plant and mycelium physics and easier and more guaranteed consumability

more concrete and simple plant and mycelium deaths, which should work in every kind of case. Along with fixes of old ideas on them and glow on the mycelium too. enjoy!

fixed the plants!

Much better optimizations for when people zoom through biomes very quickly!
