Rogue Dungeon: Vanilla Edition

• Changed the cost for spells from 30 XP points to 15.
• Changed the Return Beacon's design and it now takes away all your XP after you use it.
• Changed item rarity in chests and shulker boxes.
• Minor gameplay optimizations.

Note: This doesn't mean there will be a full version of the map. From now on, I am focusing on the Rogue Dungeon mod.
