Inventory: Make addItem for empty ItemStacks respect max stack size

When adding items to an empty ItemStack, limit the number of items taken
based on the maximum stack size in the item description.
Likewise, when checking whether items will fit into an empty ItemStack,
only absorb as many items as are allowed in a single stack and return the rest.
