The Annotation Object Scale dialog (advertised in v0.8.2) was dead code:
bare OBJECTSCALE was caught by the immediate "mark selection annotative"
arm, so the `"OBJECTSCALE" =>` dialog arm below it never ran and nothing
else opened the dialog. Move the quick mark to an explicit `OBJECTSCALE ADD`
keyword (what the ribbon "Add Scale" button now sends, dispatched whole so
it doesn't collide), leaving bare OBJECTSCALE to open the dialog.
