    display-page: Use more appr. icon for properties
    
    During GNOME Docs hackfest 2013 in Brno, Ekaterina pointed out that
    properties icon is just a 'squigly line' and is totally unintuitive.
    Everyone agreed.
    
    Looking at the mockups, I think we are supposed to use
    'preferences-system-symbolic' here:
