PrintDialog: add separate Preview/Print buttons

Browse source 
We rename our old 'Print' button to 'Preview' (as it did just that),
and add a new one called 'Print' which does the direct printing,
by creating a QPrintDialog instance. Both buttons are located
on top of the dialog for now in a QHBoxLayout.
