simplenews-block.tpl.php typo not allow issue_list list to display

There's a typo bug in simplenews-block.tpl.php which won't allow the list of recent newsletters to display.

Here's the line in question

  <?php if ($use_issue_list && $issue_list): ?>
    <div class="issues-list"><?php print $issuelist; ?></div>
  <?php endif; ?>

notice: $issuelist typo

Should be changed to:

  <?php if ($use_issue_list && $issue_list): ?>
    <div class="issues-list"><?php print $issue_list; ?></div>
  <?php endif; ?>
