    auth-dialog: don't connect to Gtk+ display until necessary
    
    In the external UI mode we may end up not needing a connection to the
    display server at all.
    
    This splits the parsing of Gtk+ command line arguments from connection
    to the display. This also fixes the --help output to actually include
    the Gtk+ arguments (such as --display).
