Update required

Updated required to remove warning due to:

As of 3.5, wpdb::prepare() enforces a minimum of 2 arguments.

I suggest the following changes in stb-admin-class.php on lines 982 and 983.

$trash_num = $wpdb->get_var($wpdb->prepare("SELECT COUNT(*) FROM $sTable WHERE trash = %d", 1));
$active_num = $wpdb->get_var($wpdb->prepare("SELECT COUNT(*) FROM $sTable WHERE trash = %d", 0));
