If arrow stack is 64, use Quiver texture (CIT)

Using MCPatcher's Custom Item Textures feature, I made it so that if arrows is in a stack of 64 items, it will use the `quiver.png` texture instead of the `arrow.png` texture.

This requires MCPatcher because Optifine does not have CIT at this time.
