Quiver and Offhand Slots

Currently trying to decide how to handle different arrow types and thinking of a quiver slot.  Would have the result that arrow types can't be readily swapped between but I'm not sure if this is a negative or a positive.  The bomb arrow is about done except for this part. I also want to add the offhand slot where you can either equip a shield or a torch. So I'm probably going to delay the bomb arrow slightly and focus on how the player inventory screen will look.  After a few bug fixes going to release a new version for today.
