Reworked Keep Inventory

Player Facing Changes

• Items dropped from the Allay when the player's inventory is full now is invulnerable (meaning it can survive lava, explosions, etc) and has a 15 minute despawn timer.
• The Unbreaking enchantment now affects the durability penalty.
  • Unbreaking 1 is a 12.5% penalty, Unbreaking 2 is a 10% penalty, and Unbreaking 3 and above is a 7.5% penalty.
  • Unbreaking penalties can be changed in data/reworked_keep_inventory/item_modifier/damage_gear_unbreaking_#.json, # being 1, 2, and 3.
• Creative and Spectator players will now no longer spawn an Allay or drop items from their inventory upon death.

Technical Changes

• The dummy item the Chest Allay carries is now an allay_spawn_egg with its entity data set to null and it's item model set to a chest. The previous dummy item was a poisonous potato which Chest Allays would pick up if left around on the ground.
• The Chest Allay's PortalCooldown and DuplicationCooldown is now -1L, previously being 2147483647.
• The damage_gear function has many more checks to accomodate for the Unbreaking enchantment, despite all these checks, this should not impact performance all that much as it only executes once when a player dies.
