Make the EWS Configuration dialog fit on small screens
Make the EWS Configuration dialog fit on smaller screens by putting the contents of the tallest tab into a scrollable area.
This change is not entirely satisfactory. The dialog is smaller, and shrinks even further on smaller screens, but I would like the default size on 1920×1080 screens to be big enough to remove the scroll bar, and I couldn't find any combination of sizeHints and QSizePolicies that did that.
