Classic drop mode update:

Shulker boxes now act as containers that do special things when placed inside of the custom drop inventory:

Red Shulker Box:
When the red shulker box gets dropped, it automatically releases all its content, meaning you can now drop multiple items at once (good for gears for example)

Yellow Shulker Box:
Expands the custom drop inventory by 27 slots. DropEdit will add all items configured in a yellow shulker box to the pool of items from which DropEdit chooses a random item afterward.
