commit dc52c6d45d05841b916c61c454666fd99cc52372

    Allow choosing whether to open in recently-used mode, last-used-folder mode, or
    
    This works by having a GKeyFile, in ~/.config/gtk-2.0/gtkfilechooser.ini and reading this:
    
    [Filechooser Settings]
    DefaultFolder=cwd|last|recent
    
    That is, the DefaultFolder key can have values of 'cwd', 'last', and 'recent'.  The default, if
    the key is not set, is 'recent' - this will bring up the recently-used mode as usual.
    The 'cwd' mode will use  instead, and 'last' will restore the folder that was used
    in the last instance of the file chooser in any application.
    
    We use that config file in ~/.config/gtk-2.0, not in gtk-3.0, so that it *is* the same config
    file as used in GTK2 applications.
