Breaks with Webform 7.x-4.0-rc1

Hello,
First, love this module!! I recently updated to Webform 7.x-4.0-rc1. After the update, my Webforms that included value sets were broken with an error message: "Missing argument 4 for values_webform_webform_select_options()."

Upon investigating the Webform changelog, it looks like this issue causes the problem: https://drupal.org/node/2064851

It appears that a very small change is needed to values_webform.module

Changing from:

/**
 * Callback for the select options list
 * @param  string $value_set_name
 *         The name of the value set to load
 * @return array
 *         An array of optionn of options
 */
function values_webform_webform_select_options($component, $flat, $filter, $arguments) {
  return values_load_options($arguments['name']);
}

to:

/**
 * Callback for the select options list
 * @param  string $value_set_name
 *         The name of the value set to load
 * @return array
 *         An array of optionn of options
 */
function values_webform_webform_select_options($component, $flat, $arguments) {
  return values_load_options($arguments['name']);
}

seems to resolve the issue (remove $filter). I can submit a patch if that's preferred for testing.

Thanks!
Joy
