Bug 254696

Version:           2.2 (using KDE 4.5.2) 
OS:                Linux

The custom slide show editor uses two buttons, one for adding a slide and one for removing a slide.  I think instead drag-and-drop should be used

Specifically:

1. you can just drag slides from the "available slides" list to the "current slideshow" list to add slides

2. you can drag the slides within the current slide show to reorder them (you can't reorder them at all right now).

3. you can drag drag one or more slides to a different slide show in the slide show list to add them in that order there

4. You can drag slide from the current slide show list to either the available slides or outside the window to remove them from the current slide show

Reproducible: Always
