Fixed popups getting blocked by modal windows.
In the case of a file dialog with a completer, the completion list view
is a popup that is not a transient child of the file dialog. Thus it
ends up getting its blockedByModal flag set due to the file dialog
window being a modal window.
To prevent this we make sure popups don't get blocked by modal windows,
as they were special cased and processed before modal windows in Qt 4.x.
