All Falling Damage

all falling blocks will take damage
Sand, red sand, dragon eggs, that sort of thing
added damage to all falling blocks, except for the anvil. The damage is calculated by falling distance, and the distance of a block is 1 damage
there is also a command to adjust the mode
/everything_hurts
there are 4 modes
1.default (acquiescent)
2.mode1 (It's going to keep generating the same blocks as it goes down)
3.mode2 (The falling beepers become the beepers that the ground touches)
4.mode3 (The cube lands and disappears)
给所有会下坠的方块都添加了伤害，除了铁砧，伤害是用下坠距离计算的，一个方块的距离就是1点伤害
