Add gems that can be combined with weapons and armour for different effects.
Example: Garnet on a sword would cause fire damage, but on a chestplate would reduce fire damage.
Weapons and armour mobs drop have a chance to have sockets for gems to be inserted.
Some mobs drop gems of varying qualities.
The gems can then be added to socketed items in an anvil.
Imperfect gems can also be combined with other gems of the same type in an anvil to result in a gem of better quality.
WIP, be prepared for bugs.
