fix(refedit): write the whole definition back to an xref, keep a .bak

REFCLOSE Save on an xref replaced the referenced file's model space with
the working set alone. With the Nested selection method the objects that
were not checked out stay in the definition, but they were deleted from
the file on disk. Write back every object of the saved definition, and
copy the file to .bak first when ISAVEBAK is on, as a drawing save does.

Also translate the new REFEDIT prompts into the other 20 locales; the
catalog test requires every locale.
