    contrib: Allow browsing all icons in icon_names
    
    icon_names is a handly tool but not a real Kupfer plugin (not for
    enduser use). now it can browse all icon names in the gtk icon theme.
    
    Note: not any icon name found in the current theme can be used for
    Kupfer, we must always try to use icon standard names or gtk stock
    icon names when possible.
