Just a quick compatibility update for The Flattening changes, with a few bonuses. Most new blocks and mobs are still missing.

NEW STUFF
* Added Beds: 16 different variations, not just the same bed with different colors.

TWEAKS
* New design for Ice, slightly different Packed Ice.
* New leafy Sugar Cane with random variations.
* Fixed biome color variations being unnoticeable at default Biome Blend video option (5x5).
* Removed my custom font because I have no idea how to make one with the new font system!
* Water no longer has a realistic color (blue af) because Mojang hardcoded it, but see below.

OPTIFINE ONLY
* Realistic water colors are restored thanks to Optifine. Excessive Transparency was partially fixed but the scarcity of underwater "fog" makes it impossible to properly simulate it.
* Fixed lighting at dawn/sunset being too dark, and made it a litte more colorful.

ADDENDUM
* A new addon pack, Addendum: Textiles, adding fancy motifs to Wool blocks and Beds.
