Comment #3 on issue 645 by tudor.gi...(a)gmail.com: we should keep the
current selected tab in the moose panel

Finally this is fixed.
Or at least, we have a better solution. We now display the presentation
with the same title as the one of the last pane that was removed. It seems
to work reasonably well.
