fb_graph module needs correct hook implementation of permissions

Hi,

The moduel fb_graph needs change the fb_graph_perm to fb_graph_permission

OLD

function fb_graph_perm() {
  return array(FB_GRAPH_PERM_PUBLISH, FB_GRAPH_PERM_DELETE_OWN);
}

NEW (Somelike this)

/**
 * Implements hook_permission().
 */
function fb_graph_permission() {
	return array(
			FB_GRAPH_PERM_PUBLISH => array(
					'title' => t('Publish to graph'),
					'description' => t('User can publish to graph.'),
			),
			FB_GRAPH_PERM_DELETE_OWN => array(
					'title' => t('Delete own graph from timeline'),
					'description' => t('User can remove their graph from timeline.'),
			),
	);
}
