| It seems we need "selection only" plugins. That is plugins which should
| only be enabled if images are selected. I suggest the following:
| - Add a slot named Interface::slotSelectionChanged() and a KIPI feature
| named SelectionOnlyPlugin.
| - The host app should call Interface::slotSelectionChanged() when the
| selection changes.
| - slotSelectionChanged() should loop on all plugins with the
| SelectionOnlyPlugin feature and disable or enable them if there is a
| selection.
The host application already do emit signals, among these 
selectionChanged( bool hasSelection );

Wouldn't it be better to connect it to such signals?
