Filtering bug fix

In /sermons.php,
line 250: public static function fix_sermons_ordering( $query )

public static function fix_sermons_ordering( $query ) {
		if ( ! is_admin() && ( $query->is_main_query() ) ) {
			if ( is_post_type_archive( 'wpfc_sermon' ) || is_tax( sm_get_taxonomies() ) ) {
				$orderby = SermonManager::getOption( 'archive_orderby' );
				$order   = SermonManager::getOption( 'archive_order' );

				switch ( $orderby ) {
					case 'date_preached':
						$query->set( 'meta_key', 'sermon_date' );
						$query->set( 'meta_value_num', time() );
						$query->set( 'meta_compare', '<=' );
						$query->set( 'orderby', 'meta_value_num' );
						break;
					case 'date_published':
						$query->set( 'orderby', 'date' );
						break;
					case 'title':
					case 'random':
					case 'id':

Case “id” needs to be “ID” or wrap $orderby in a strtolower()…

Without this change, the option to sort by ID in the admin settings will not work.
