MC-136865: Pass original itemstack for enchantment checks on block break When an itemstack runs out of durability, the amount is reduced to 0 which then marks the item as invalid. This causes the last unit of durability to not apply enchantments as the enchantment level check sees the item as a dud. keep the clone of the item used to a non empty value so it represents the item used.

Optimize Small Entity Movement Optimizes small movements by entities by merging the movement into the entities next larger movement, until enough movement velocity has been hit. This reduces collision detection and able to reduce movement cpu cost by 5-7%. The default option of 0.75 seems to provide all the gains without any noticable behavior change to entity movement. We have to exclude slimes due to weird jumping animation bugs.
