Change subject: Allow passing index when adding a Reference to a ReferenceList
......................................................................
Allow passing index when adding a Reference to a ReferenceList
In order to allow more flexibility when adding a Reference to a ReferenceList,
an index may be specified. This allows inserting a Reference at an other place
than at the end.
