Support additional options added via hook_user_import_form_fieldsets

I wanted to add an option to the "Options" fieldset have have that option saved into the Options column.

I did this by adding another element to the 'optional' fieldset in my hook_user_import_form_fieldsets.

Example:

  $form['optional']['force_password_change'] = array(
      '#type' => 'checkbox',
      '#title' => t('Force password change'),
      '#default_value' => empty($import['options']['force_password_change']) ? 0 : $import['options']['force_password_change'],
      '#description' => t('Force the user to change their password on first login.'),
  );
  
  return $form;

However, I then needed to make some changes to the user_import.inc and user_import.module files to allow the saving to the options column.

In user_import.inc, added '#tree' => TRUE, after line 102.

Result is:

  $form['optional'] = array(
      '#type' => 'fieldset',
      '#title' => t('Options'),
      '#tree' => TRUE,
      '#weight' => -85,
      '#collapsible' => TRUE,
      '#collapsed' => $collapsed, 
  );

Remove or comment out lines 1201-1204. Next, I added the following lines after line 1196 in user_import.module (in the _user_import_settings_save function)

    // Settings that have their own column
    $columns = array('name', 'pointer', 'processed', 'valid', 'first_line_skip', 'contact', 'username_space', 'send_email', 'field_match', 'roles');
    
    foreach ($settings['optional'] as $option => $value) {
      if (!in_array($option, $columns)) {
        // This will capture any options that are added to the "optional (Options)" fieldset via
        // the hook_user_import_form_fieldsets.  It will also capture the 'activate' setting as well.
        $settings['options'][$option] = $value;
      }
      else {
        // This will capture options that have their own columns
     		$settings[$option] = $value;
      }
    }
    // We're done with the 'optional' array, so let's clean up
    unset($settings['optional']);
    

I have attached a patch for the two files.
