Subject: [PATCH 50/54] Reintroduce the Advanced tab in the
 QPrintPropertiesDialog

This is mostly a revert of 69de6177615de3c4c31dea529172389e92f490b0 adapted to the new code.

The commit that removed this code said:
 a) there's duplicate settings in the advanced tabs and in the rest of the ui: this easily
    solved with a blacklist
 b) you can set these options in the system settings: probably true, but it is very cumbersome
    to go to the printer settings every time i print to select from which tray the
    paper should be used

Task Number: QTBUG-54464
