OnOwnershipSquelchMailtoQueueWatchers

This is a scrip action that I found multiple requests for while I was looking for it myself, but I couldn't find any example of code that did what I wanted it to do:

If a ticket goes from being owned by "Nobody" to being owned by a regular user, anyone who is just an AdminCc because they are assigned as a Watcher for that Queue. If they're the Requestor, Owner, or have been assigned as a CC or AdminCc for the ticket itself, they keep getting mail.

        $t->SquelchMailTo($q_u->EmailAddress);
    }
}
return 1;
