NEW STUFF
* Shulker Boxes. Since regular Shulkers behave kinda like "mimics", all of them look like regular blocks with minimal changes. All boxes include a custom Shulker head hoping one day Java Edition will allow players to color Shulkers. (this should have been included in the previous update but I messed up, sorry!)
* Structure blocks and Structur Void item, with a yellow&black stripe patter so they stick out.
* Parrots. Each variation is based on RL parrot species:
	Red/blue and yellow/blue: Macaws.
	Grey: African grey parrot.
	Green: Indian ring parakeet.	
	Blue: Cockatoo. (I really wanted a cockatoo so I had to sacrifice a texture and the blue one seemed the most boring since macaws already have blue in their feathers)
* Llamas and their decors in 16 exotic and unique variations.

OPTIFINE/MCPATCHER ONLY
* Creepers have different mimetic skins depending on biome and height, including the End and the Nether.

MOD SUPPORT
* Added partial support for Dynamic Surrounding (I didn't change the compass GUI).
* Partial support for Schopcraft; just the bars because I don't use seasons and special items, better than nothing.
* Removed support for Underground Biomes Construct because it was never updated to 1.12.
