Modified EquipmentSlot to display an image instead of a text. Added EquipmentGui class, which handles the equipment slots of the player screen. An EquipmentGui instance will be created in the InventoryGUI constructor. The initializeInventory method of the Hud class supplies the players inventory and equipment to the InventoryGUI constructor.
