Cursed Worlds

Adds a few cursed and broken world types.

Select the type of world in the world creation screen, or alternatively, (mainly on servers) set the gamerule cursedWorldTypeId to one of the following, to change the cursed world type:

0: None, 1: Tall Cliffs, 2: High Mountains, 3: Blox/Islands, 4: Broken Amplified, 5: Bumpy/Spiky, 6: Spiky/Cliffs, 7: Holes/Spiky, 8: Mangrove Stripes, 9: Mountains/Walls, 10: Brutalist Stone Architecture, 11: Islands/Shrooms

After setting the game rule, a server restart is required for the changes to take effect.
