Modified dialog for googlefetcher.  It now shows all (up to the first 20) results from google as thumbnails.  It also shows the size (in pixels and KB).

Can someone make sure I'm using the KIO stuff correctly?  It's my first code with it, and I'm afraid of buffer overruns, memory leaks, etc.  I used code from other parts of kde as a reference.
