Once again the NSOutlineView

[Andreas Heppel]

Hi list,
I have again stumbled across some strange behaviour in NSOutlineView. This 
time it has to do with reloading items.
The method -reloadItem:reloadChildren is using another method called 
_findItem:childIndex:ofParent:. I suppose that this method is intended to 
return the parent and the index relative to this parent of the given item. 
Unfortunately, it is not, as the parameter 'parent' is not by reference.
Furthermore, -reloadItem:reloadChildren does not update NSOutlineView's data 
structures _items and _levelOfItems, which leads to some more starnge 
behaviour in the case that the NSOutlineView's delegate does not simply return 
a changed item, but a new one. Maybe, this behaviour is intended, as the 
delegate is supposed to return the same, but changed item. However, fixing 
this is not difficult imho, thus, I'd prefer to change this behaviour. 
Attached is patch with a fix, containg a couple of detailed comments on what I 
did.
Please anyone comment on this. Thanks.

Andreas
