Extra Armor Slot

First CurseForge release.

• Extra armor column next to the normal armor slots, in the survival and creative inventory.
• Armor, toughness, attributes and every armor enchantment stack with your normal armor; extra armor wears down and drops on death like normal armor.
• Raised armor and protection caps: each extra set adds another layer (never full immunity). Can be turned off in the config.
• Other mods see extra armor as worn, so their set bonuses work from the extra slots.
• Elytra, turtle shell, carved pumpkin, gold, leather and mob heads work from the extra slots.
• Up to 10 extra sets with the extraArmorSets config option; columns page when the screen is too narrow.
