If we agree on having libkipi (not the host app) supply a widget for album 
selection (I'll call it KIPI::AlbumSelector for now), then we can have an 
AlbumSelector::images() method for plugins which needs it. The current* 
methods should only be used by dialog-less plugins.
As far as I'm concerned, I think the current* methods are ok. Plugins which 
modify the images should use currentSelection() only, plugins which only read 
images should use either one of the three methods.
I don't see a need for it being virtual now, but it should not imply any 
performance cost, so I'm ok to have it virtual if you need.
