QNX: Allow creation of parentless child windows

There is no reason why a parentless window from a Qt perspective needs
to be a screen application window.  There are some cases, such as the
BB10 dialog service whose windows are always parented by a window in
another process.

Ideally one would have a means to indicate a child window was wanted that
had no other side effect (i.e. the rest of Qt would ignore).  The use of
Qt::Dialog is not ideal as some code does pay attention to this type given
the number of bits available for window type, it is not reasonable to add a
new one.  The use of Qt::Dialog seems safe since it is hard to conceive of
a window of type Qt::Dialog wanting to be a top level window.  If in future
it is required to have a parentless, child window that is not of type
Qt::Dialog one can simply define some additional way of signalling this.
