Add QHeaderView::setFirstSectionMovable(), useful for flat treeviews QTreeView makes columns movable except for the first one (since Qt 5.0, see commit e0fc088c0c). This is indeed best for actual trees, but not when using QTreeView as a flat multi-column list (with no "root decoration"). Then it should be possible to move the first column. [ChangeLog][QtWidgets][QHeaderView] Flat treeviews can now allow the user to move the first column (like in Qt 4.x) using the new method QHeaderView::setFirstSectionMovable().
