[evince/unmessify-my-pdfs: 2/3] Implement the 'Open Containing Folder' command

[Federico Mena Quintero <federico src gnome org>]

commit 5d42af6c195aa3d17047afbaeec438009fcf17ce

    Implement the 'Open Containing Folder' command
    
    Nautilus doesn't seem to like
    
      nautilus file:///home/foo/Downloads/foo.pdf
    
    these days; it complains that foo.pdf is not a folder.
    
    So, we just launch the default handler for the file's parent folder.
    When that bug in Nautilus is fixed, maybe we can go back
    to spawning it directly.
