    Open ftp URIs in external application
    
    Likely we're never going to support FTP, at least not unless a wild
    volunteer appears to implement it.
    
    So:
    
    First, try the default URI handler. It might be Firefox, which is odd
    but will work. Whatever gvfs-open picks on my computer fails with an
    error that the specified location is not mounted, so forcibly fall back
    to Nautilus if the default application did not work.
