Create ISpecialBow.java

Provides two methods allowing custom bows more control over quiver behavior.
ISpecialBow may determine nocking behavior

This is only for visual purposes, signalling the player that the current bow + arrow/quiver/inventory setup will not allow them to fire, thus saving them from wasting time pulling the bow - much like the vanilla bow when an arrow is not found in the inventory.
