Fields excluded via fields override conf overrides exlusion set via views object/UI

In ctools/views_content/plugins/content_types/views_panes.inc:

278   if ($allow['fields_override']) {
279     if ($conf['fields_override']) {
280       $fields = $view->get_items('field');
281       foreach ($conf['fields_override'] as $field => $display) {
282         $fields[$field]['exclude'] = empty($conf['fields_override'][$field]);
283       }
284       $view->display_handler->set_option('fields', $fields);
285     }
286   } 

You see on line 282, it bases the exclusion of the fields only on whether the config of the fields override is set or not. This can lead to a scenerio where a view is built, the fields override config is set to FALSE (= show the field). Later, the field will always show up if the field is excluded even in the views UI.

here is a patch. I feel there is more work to be done for the admin form. but this is a start.
