Searching multiple zones

[tool4ever]

After refactor of 19cca4ce ChangeZoneAll effect still has a big code chunk related to library searching.

• [x] However only one remaining script actually uses it: Haunting Echoes which could be updated to ChangeZone easily

• [ ] But maybe the previous scripts also need an improvement as they would currently lead to multiple events of zone changes, e. g. Counterbore finding graveyard and library cards should probably still trigger Laelia only once, not twice?

• [x] There are also multiple other cards still carrying a now non-existing Search$ param for clean up
