DisplaySettings: Don't crash after 'pape'

Browse Source 
Running 'pape' without arguments (or just editing the WindowServer.ini by hand)
can confuse DisplaySettings. Specifically, if the 'Wallpaper' is set to
'/res/wallpapers/', then DisplaySettings used to crash because 'name_parts'
wouldn't contain any trailing element.

It's hard to define desired behavior, but this is better than crashing
and confusing the user.
