API: Add event when magnet flag is sucking up an item

[EpicEricEE]

This event is firing everytime the magnet flag/module is pulling an item into a chest.

I would need that as an API call for my resource, because it has a floating item (similar to Showcase) above a chest which is currently always being pulled into the chest that is not what it's supposed to do.

Probably other developers would need that too.

Sorry for any language mistakes
