Indirect ghost destruction should trigger an event

[NiftyManiac]

When a ghost is destroyed via right-click, on_preplayer_mined_item is raised (but not on_player_mined_item, since there's no item stack).

However, when a robot places an item (causing the ghost to be removed), or when a ghost disappears due to the player placing an overlapping item, no event containing the ghost is fired. I think it'd be good if there was a consistent event representing the disappearance of a ghost.

Does there exist any method for detecting the second case? When on_entity_built is raised, the overlapping ghost is already gone. When on_put_item is raised, you can check if there's a ghost at the given position, but you don't know the size of the entity being placed to check for overlap. I suppose an ugly solution would be to store all of the nearby ghosts with on_put_item, and then check if any of them no longer exist when on_entity_built triggers.\

Edit: forgot that ghosts are also destroyed when marked with the deconstruction planner. This seems completely undetectable, since neither on_marked_for_deconstruction nor any other event is triggered. Even more reason to have a unified way to track ghost disappearance.
