Print: adjustments to PrintDialog

- Hide the sizeing sliders from PrintOptions. we don't really
support any of those in PrintLayout and these are not that
useful and easy to implement, until some sort
of layouting/templating system is in place.
- Move the 'Print' button on top as a workaround, since if
it's bellow the print options it stays bellow an empty area
where the now hidden sizing sliders are.
- Resize the dialog to a smaller size
