Stuff

In the lib/config.php simple add the is_tax to the conditions array and then the name of the template to the second array like so,

array(
      'is_404',
      'is_front_page',
      'is_tax'),
    /**
     * Page template checks (via is_page_template())
     * Any of these page templates that return true won't show the sidebar
     */
    array(
      ....
      ....
      'taxonomy.php',
      'taxonomy-{taxonomy_slug}-{taxonomy_value}.php'
    )

For a list of all the available conditional array values have a look here.
