drupal_add_css arguments type and media given as null

On line 224 of fasttoggle.module the $type and $media arguments for the drupal_add_css function are given as null. These should probably be given proper values, like in the following example:

drupal_add_css(drupal_get_path('module', 'fasttoggle') .'/fasttoggle.css', 'module', 'all', false);

Unless there is a good reason to pass null values instead...
