[nautilus/wip/corey/rework-clipboard: 3/4] files-view: Allow pasting from G_TYPE_FILE

    files-view: Allow pasting from G_TYPE_FILE
    
    Copying / pasting within Nautilus is always handled by NAUTILUS_CLIPBOARD
    (GDK_TYPE_FILE_LIST), but sometimes, copying outside of Nautilus
    may pass a G_TYPE_FILE.  Now that the clipboard handling has been
    simplified we can accept these other types.
    
    Issue 540 is actually an issue related to G_TYPE_FILE, not the image
    itself.
