Ex Nihilo Adscensio

FIXED:

• Multi-sieving should no longer throw items 20 blocks into the air, unless you have a block on top. Solution: Don't put a block on directly on top of the sieve.
• Infested leaves should hopefully no longer bug out on servers.
  Also, infested leaves shouldn't infest themselves anymore.
• Fluids should now properly transform in barrels if the transforming block is on the same level as the barrel.

CHANGED:

• Silkworm food saturation nerfed pretty heavily. This wasn't my choice.
• Infested leaves can now be sheared. They will just drop themselves though, no string dupe for you.

ADDED:

• The multiplier for crooks on vanilla leaves is now configurable.
