Review of the previous commit: "Import scaled element" and "Import DXF"
add a definition to an open symbol through OpenElmtCommand, which, unlike
a paste, kept the imported terminals' uuids. With derived uuids, an old
symbol imported into itself (or into another with a terminal at the same
point) gave two terminals one uuid; importing any symbol whose terminals
already carried uuids did the same before this series. OpenElmtCommand now
renews the imported terminals' uuids, as PastePartsCommand does.
Checked in the editor with a stand-in scaler at scale 1: open
6es7_212-1ae40-0xb0__p3.elmt, import it into itself, save -- 6 terminals,
3 distinct uuids without this commit, 6 with it, the original 3 keeping
their derived values.
