Subject: [PATCH] InventoryClickEvent getClickedInventory

Add InventoryClickEvent.getClickedInventory. Adds BUKKIT-4495
Plugins currently have to do the logic themselves on the raw slot ID
in order to determine the inventory clicked. This provides the logic for plugins to
readily identify which inventory was clicked.
