[TxMt] [488] Auto-Update and non-admin account

[Gerd Knops]

There is another minor buglet with the auto-update: My TM lives on a  
network drive (shared applications). So TM complains about not being  
able to move the old version to the trash. When deleting something on  
that partition from the Finder, it also always warns that items will  
be deleted immediately and not moved to trash.

But despite that alarm auto-update went smooth otherwise.
