This action is processed when trying to add a value to a multi-valued
property. It retrieves its parameters from
AddPropertySimpleValueForm ,
then, if the property is simple this action forwards to
AddPropertySimpleValue to let the user give and add a new
value to the property, else it creates and adds a new empty
PropertyStructure value to the property and
redirects to the EditPropertyValue action to let the user
edit the new added value.
