[appearance] Make slideshows visually distinct
The patch fixes the tooltips to not lie about the backgrounds, and adds a stacked frame decoration around slide shows. This patch adds two little buttons below the slide show that let you step through the frames of the slide show, to see whats in it. Fixes http://bugzilla.gnome.org/show_bug.cgi?id=591375
