For bug #1710.  Change the ID type of mime data for filterbox drop events to Referenceable rather than using the ID's native type.
Let the filterbox of the receiving side of the drag&drop to decide whether to add referenceable type.  Only added if the table has "Referenceable ID" column AND the UniversalId type is referenceable.
