this is a the base class for all major config dialogs.

Usage:
Create a config array like
  [xxxxx/aaaa bbbb]
Create a Glade file (in the modules or transports directories with mapped objects named like
   xxxx_aaaa_bbbbb


create the object using both this data
  $conf = new &conf->config_dialog_generic($glade,$config_array);
  $conf->btn_ok->connect("pressed",array(&$this,"update_config"));
  
  to display it:

    $conf->show();
  
  function update_config() {
    $new_config_array = $conf->get_results();
    $conf->hide();
