Only show questions in the same language as the quiz

OK so I should have waited till it was a bit more useful before posting.
This version makes available to the quiz questions in any language if the language of the quiz is not set and any questions that do not have a language set.

Oh and I fixed a stupidity in the helper function :) (which I placed at the end of the module BTW)

/**
 * Get the language of a node if i18n installed
 *
 * @return
 *  node language or ' '
 * 
 * @ingroup helper functions
 */
function _node_get_lang($node) {
	$node_lang = "";
	if (function_exists('i18n_node_get_lang')) {
		$node_lang = i18n_node_get_lang($node->nid);
	}		
	return $node_lang;
}

in

function _quiz_get_unused_questions($quiz_vid = NULL, $nid_keys = FALSE) {

from line 1690:

	// Only include questions in the same language as the node (if the node has an assigned language)
	$quiz_lang = _node_get_lang($quiz);
	
  // Create questions array.
  if ($nid_keys === FALSE) {
    while ($node = db_fetch_object($result)) {
			$node_lang =  _node_get_lang($node);
			if (empty($quiz_lang) || empty ($node_lang) || $quiz_lang == $node_lang) {
				$questions[] = quiz_node_map($node);
			}
    }
  }
  else {
    while ($node = db_fetch_object($result)) {
			$node_lang =  _node_get_lang($node);
			if (empty($quiz_lang) || empty ($node_lang) || $quiz_lang == $node_lang) {
	      $n = quiz_node_map($node);
	      $questions[$n->nid] = $n;
			}
    }
  }
  return $questions;
}

OK here's a patch for this issue against the 5.x-2.0-rc1 version. Please review and comment.
