Allow plugins to change mayPickup() logic.

[WillyTheWorm]

Is your feature request related to a problem?

When using OnCraftingEvent or similar, you can change crafting results using setResult(), but the player is unable to remove the item from the crafting GUI.

Describe the solution you'd like.

Allow plugins to change mayPickup() logic, so it is possible to change crafting outputs and allow the player to remove them from the GUI.

Describe alternatives you've considered.

A workaround is to just create a recipe, but this can be tedious, and there are limitations that mayPickup() would fix.
