the class InventoryController method onInventoryDrag.

    // This could possibly be narrowed down to events only effecting held item slots and armor

    // this is a huge hack! :\
    // I apologize for any weird behavior this causes.
    // Bukkit, unfortunately, will blow away NBT data for anything you drag
    // Which will nuke a wand or spell.
    // To make matters worse, Bukkit passes a copy of the item in the event, so we can't
    // even check for metadata and only cancel the event if it involves one of our special items.
    // The best I can do is look for metadata at all, since Bukkit will retain the name and lore.
    // I have now decided to copy over the CB default handler for this, and cancel the event.
    // The only change I have made is that *real* ItemStack copies are made, instead of shallow Bukkit ones.

        // really know what happens or how you would drag more than one.

        // and skip updating the inventory.
