Add QModelIndex::siblingAtColumn and ::siblingAtRow
Data in item models is most often organized in rows, where each column
contains an attribute of the item represented by the row. Often when
sibling is used, it is to request another piece of data from the same
row. Having a specialized version makes this easier and less awkward
to do, simplifying
auto sibling = index.sibling(index.row(), columnOfInterest);
to
auto sibling = index.siblingAtColumn(columnOfInterest);
For symmetry reasons, siblingAtRow(rowOfInterest) was also added.
