Tweak admin 'Action' to avoid Cannot call delete() after .distinct()

[Mike Dewhirst]

I am using tweaked querysets to populate the Admin and fully understand
why this error occurs.

I am using Actions to perform bulk operations on selected records so I
do need the Action selector widget.

How can I remove the 'Delete selected...' option?

Thanks

Mike
