Rare biome rework

[Vinywar123]

Updates a bunch of the older biomes to fit in more with the rest of the game and just adds some more polish to them

The Crimson Wasteland is filled with magma lava and spikes as far as the eye can see Deposits of iron can be found in the magma pools that infest this place The knitted valley, a small growth of unnatural plants emerge from strange soil in this garden sheilded by mountains Flowers and hills fill the tuften valley The forests begin to mutate, grow and shrink the leaves tun into bulbous glassy groths and the ground turns to stone and cracks apart The glass forest mutates from trace uranium deposits the sky fills with unateral clouds and if faintly one can see shimmering diamonds high in the sky

did biome formatting change or is the thing just wrong?
