KFileDialog: "Parent Folder" button

[Peter Penz]

Hi,

Pretty much Gwenview and Dolphin users requested having a kind of "Go 
Up"/"Parent Folder" functionality for the URL navigator.

I've just committed a patch on trunk and it seems to work quite well. But now 
the "Parent Folder"-button in KFileDialog is not required anymore, as this 
button is already part of the URL navigator.

I know during KDE 3.x there had been a lot of discussions regarding the order 
of the "Parent Folder", "Back" and "Forward" buttons inside KFileDialog. As 
the "Parent Folder" is now available in the URL navigator, the order of the 
buttons would be changed.

Now I temporary removed the "Parent Folder" button of KFileDialog on trunk to 
get some feedback. If this solution is not acceptable, it won't be a problem 
to add a flag to the URL navigator to hide the "Parent Folder" button.

Any feedback would be very welcome :-)

Thanks,
Peter
