Bright Extreme Hills

Converts the dark green grass and trees of the extreme hills biome to the bright green used in alpha v1.1.2_01 and before. Fitting since the extreme hills biome was release Minecraft's last remnant of wacky old beta world generation!

Tested on release 1.1, 1.5.2, 1.6.4, and 1.7.10. Expected to work back to the introduction of extreme hills in beta 1.8 up to 1.16.5; and may work all the way to modern versions, but I have not tested. No guarantees in later version compatibility since all the new biomes and worldgen are so crammed as to make editing the vanilla colormaps basically impossible, and I didn't want to introduce a dependency on Polytone or Optifine/MCPatcher.

Pack variants:

• 1.0_texture-pack: the old texture pack format, for beta 1.8–release 1.5.2
• 1.0_vanilla: new resource pack format, for release 1.6.1–release 1.16.5
• 1.0_optifine-default: same as 1.0_vanilla, but includes the properties files from Optifine's default (1.12.2) resource pack, so connected glass/bookshelves and "natural textures" work correctly (for some reason some Optifine versions fall back solely to the Minecraft assets without including their own default textures when files aren't present in the current resource pack). Note that this will only work until release 1.12.2 due to The Flattening breaking the block IDs used in the property files.
