This extends behaviour of left-clicking column header which is not used for sorting yet in an ETree/ETable in a way: a) alone left-click behaves like before, all current sorting is dropped and the ETree/ETable is sorted only by that column b) left-click with pressed Ctrl key adds the column as the first to sort by c) left-click with pressed Ctrl+Shift adds the column as the last to sort by
