Shift Click = Submits all items in inventory into fishy block (Mass Submittion)

Shift left click with the correct item, it will then cycle through your complete inventory and transfer every matching item to the fishy block. Tested and works. Enchantments disabled due to weird things happening and will be better if the player maintains this manually, never mind the fact I never see somebody trying to submit 10 double chests full of the exact same book into a fishy block. Normal left clicking does work still obviously.
