Fixed wrong lantern state by tracking equipped vs inventory separately

[Infinitay]

There was an issue with v1.5.0 after adding support for decay prevention gear such as always thinking the player has a lantern. This fixes that.

• Track two different states for the abyssal lantern - equipped or in inventory
  • Refactored hasRedwoodAbyssalLantern into hasRedwoodAbyssalLanternEquipped and hasRedwoodAbyssalLanternInInventory
  • Added #hasRedwoodAbyssalLantern helper method
  • Refactor ItemContainerChanged event to set the new abyssal lantern properties appropriately
