Loot Bag

• loot bags are not stackable now.
• The loots of a loot bag will change depending on the biome the creature is killed in.(not related to where you open the bag)
  e.g.
  If you obtain a loot bag in the jungle, you can only get chests/jungle_temple, chests/simple_dungeon, chests/ruined_portal and chests/abandoned_mineshaft
  (loot from a simple dungeon can be obtained in any biome and is more likely to be obtained than other loot)
• Loot tables of nether fortress and ancient city have been added.
• Frost wand can only be obtained in the cold/snowy biome.
• The probability of obtaining extra gifts has been reduced.

Only tested in single player mode!
