[1.1.5] 1.1 ghost building changes impact usability of LuaSurface.can_place_entity

[shanemadden]

The build_check_type flag on LuaSurface.can_place_entity was added (viewtopic.php?f=65&t=57632) in response to my need to check if a ghost was already present at a position for this mod: https://mods.factorio.com/mod/replicating-belts

In 1.1, the new rules allowing placement of overlapping ghosts (even with the same orientation as the original ghost) has broken the use case of checking if a ghost is already present. Could the function return a failure if the new placement does not rotate, instead of just saying all ghost builds are valid (which seems fairly useless)?

In general ghosts should not be placeable on top of each other but there are some exceptions like ghosts from different forces. I will move this topic to pending because there was another batch of changes related to buildability checks for 1.1.6, one of which changes`build_check_types` so i will not be checking what is your particular issue right now in 1.1.5. When 1.1.6 will be out, let me know if its still broken or if it was fixed.
