Title: More sets handling improvements

This PR contains the changes i was working on in #449.
Four buttons have beed added to move sets around (up, down, top, bottom);
Drag&drop sorting has been fixed (it was forcing an immediate save);
The ID column has been hidden;
The QSortFilterProxyModel has been removed to permit custom sorting (moving around items using the buttons).
