Zombie Villagers drops emeralds

This is a new game mechanic introduced on the Villager Tweaks Mod.

Whenever a zombie villager dies, they have a small chance to drop a single emerald.

The base chance is 15%. In case they are killed using a Looting enchanted weapon, every Looting level adds 5% to the base chance, so a Looting III sword would raise the drop chance to 30%. The amount of emeralds however won't be affected.

In case the zombie villager was about to drop an iron ingot, the emerald code is skipped, so no zombie can drop both items.
