refs #768, allow reselection of values when a view is sorted

Browse Source 
* reselect callbacks
* remark: Only working in some cases as sorting is part of the model, while selection is part of the view (and sorting can take place without the view knowing the model is sorted)
* allow to sort by property index
* renamed to m_sortColumn
