SG Mob Trims

When a skeleton or a zombie spawns with some armor piece, it has a 50% chance to have an armor trim applied to its whole armor only in hard difficulty. The trim pattern and trim material is selected randomly so every material/pattern combination is equaly possible. The mobs can drop its armor when killed as a rare drop (that vanilla behavior was not modified), so now you can collect every type of armor with trims killing zombies and skeletons.
