Magnet ONLY picks up selected items

[BLUEChester]

It would be great if the magnet had a config option to not only attract the selected items from far away, but also act as an inventory filter and ONLY pickup the items that you select. This would make the magnet much more useful and in some cases a necessity.

Of course the player could always remove the items from the magnets inventory to stop the filter at any time.

You could also add an invert enchantment for the magnet where all the items in the magnets inventory will not be picked up, and all other items will be.

The use cases for this would be countless.

Thanks heaps for making this mod, it's awesome!
