saveConfig() does the following:

* determine what the names of the wallpaper and containment plugins are (first 
three lines)

* if the containment plugin is changing (e.g. desktop -> folderview) then 
create the new containment, swap it with the current one (that includes 
ensuring the mouse actions and wallpaper go with it)

* save the settings of the wallpaper configuration (d->wallpaper is an 
instance of the wallpaper plugin in the dialog, not in the containment)

* have the containment re-load the wallpaper settings by calling setWallpaper 
(which has that side effect)

* reset the modified state (and therefore the Apply button, etc)
