Layers: Duplicate Layer numbers copies in story order and is translated

Duplicate Layer gave the copied stories' tables and anchored objects
their new ids in hash-map order, so the ids differed from run to run.
It now takes the stories in order. The Layers panel's "Duplicate Layer"
menu item has a row in every interface language.
