/**
* To make a form auto submit, all you have to do is 3 things:
*
* ctools_add_js('auto-submit');
*
* On gadgets you want to auto-submit when changed, add the ctools-auto-submit
* class. With FAPI, add:
* @code
* '#attributes' => array('class' => array('ctools-auto-submit')),
* @endcode
*
* If you want to have auto-submit for every form element,
* add the ctools-auto-submit-full-form to the form. With FAPI, add:
* @code
* '#attributes' => array('class' => array('ctools-auto-submit-full-form')),
* @endcode
*
* If you want to exclude a field from the ctool-auto-submit-full-form auto submission,
* add the class ctools-auto-submit-exclude to the form element. With FAPI, add:
* @code
* '#attributes' => array('class' => array('ctools-auto-submit-exclude')),
* @endcode
*
* Finally, you have to identify which button you want clicked for autosubmit.
* The behavior of this button will be honored if it's ajaxy or not:
* @code
* '#attributes' => array('class' => array('ctools-use-ajax', 'ctools-auto-submit-click')),
* @endcode
*
* Currently only 'select', 'radio', 'checkbox' and 'textfield' types are supported. We probably
* could use additional support for HTML5 input types.
