diff of poppler-page.cc with needed changes

As apposed to other pdf-viewers, there is no support for Thumbnails if (I
assume) they have not built in [I have no pdf's that have them].

In the present code m_page->page->loadThumb returns false, because it cannot
find the data-stream (this being,I assume, the built in Thumbnails).

Adding the following would resolve this:

  else
  {
   ret=renderToImage();
   w=50;
   h=75;
   if (ret.width() > ret.height())
   {
    h=50;
    w=75;
   }
   ret = ret.scaled(w,h,Qt::IgnoreAspectRatio);
  }

whereby I have taken a small value for the size.
Adding this code would make the basic qt4 version of viewers more like other
pdf-viewers.
