sort fonts so that upright faces are shown in the font dropdown list

Change font sort so that font faces like those of URW Palladio L whose italic
variant is lighter than its upright variant are sorted with the upright fonts
first so we don't see italic variants in the font widget.

Also sort "normal" weight faces below all other weights
