/**
	@brief The ConductorPropertiesEditorWidget class
	Hosts the existing ConductorPropertiesWidget in the dockable selection-
	properties panel, so selected conductors can be edited in place like the
	other item types, instead of only through the modal dialog (issue #500).
	A pinned "apply to all conductors of the potential" checkbox (persisted)
	mirrors the modal dialog's option to propagate edits to the whole potential.
	When several conductors are selected, the panel shows the first one and
	applies to each only the fields the user changed.
