CubeDesigner: make ResultList2 DataMode configurable

At the moment, this script is requiered for a result list (Trefferliste) to activate the task view of a process:

Private Sub ResultList2_OnInit()

ResultList2.DataMode = resultList2DataMode_TreeMode

End Sub

It would be nice, if the DataMode Treemode could be set in the properties of the CubeDesigner (Trefferliste -> Objekt-Inspektor)
