* 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
* item delegate for callback to view for hover
* proxy style for draw drop indicator as primitive
* added functions to view base for hover / callbacks
* highlight hover row in model
* allow upfront checking of formatter roles
* selection mode menus adjusted (data approach no longer worked with CSlot)
* removed unused style sheet parts
* minor View/Model tweaks/formatting
* set sort order automatically to IndexOrder when changing order of items
* call onChanged when model is changed and then update view (needed when model is changed directly, not via view)
* support for digest signal so redundant updates can be avoided
* renamed rowCountChanged (signal) to modelDataChanged - detecting row count changes only was useless
* updated Doxygen / fixed typos
