[PATCH] fix rename crash in Konqy

[Michael Brade]

Hi!

Somehow I have the feeling almost nobody knows how KDirLister works :-\ The 
attached patch essentially reverts AleXXX hack^Hcommit from 5 months ago, 
removing the renamingFinished() method in KonqBaseListViewWidget and 
KonqIconViewWidget. In combination with John's patch (which nobody seems to 
have tested) it crashes Konqy.

Here's why: if the renaming succeeds KDirLister will emit deleteItem() and 
newItems(). So in the listview's renamingFinished() m_renamedItem is not 0, 
but a dangling pointer and the call to m_renamedItem->updateContents() is the 
reason for the crash.

In general, if after renaming a file with F2 the file is shown with a wrong 
name it is the fault of KDirLister not emitting the correct signal or a bug 
in the implementation of the slots connected to its signals.

I fixed the iconview as well, using the correct part of John's patch ;-), that 
is, testing if the new name is empty. There, we didn't crash Konqy because we 
don't delete the removed item for some reason I don't know, I'll change that 
after KDE 3.1 to prevent unwanted/unknown crashes. (the iconview seems to 
need some cleanups anyways...)

Please review, this definitely needs to go into KDE 3.1.
