DisplayProperties: Wallpaper tab now has preview

Browse Source 
As was mentioned in #556, the `DisplayProperties` Wallpaper tab
contained a lot of "extra space", in which half the tab was taken up
by the list of wallpapers. The rest of that space is now reserved for
a wallpaper preview, so the user can see the selected image before
applying it.
