Add Cirkuit Theme to TinyMCE

The Cirkuit Theme as patched here does not appear to support the button icon for the Visualblocks plugin, which is useful for visualizing divs, tags, spans, etc. Granted, this plugin must be added manually. Ex:

/**
 * Implements hook_wysiwyg_plugin().
 *
 * Adds the option for the Visualblocks button in the settings form.
 */
function HOOK_wysiwyg_plugin($editor, $version) {
  $plugin = array();

  $plugin['visualblocks'] = array(
    'buttons' => array('visualblocks' => t('Visual Blocks')),
    'url' => 'http://www.tinymce.com/wiki.php/Plugin:visualblocks',
    'load' => TRUE,
    'internal' => TRUE,
  );

  return $plugin;
}

This patch's only difference is to add the icon back.

@jessehs: Thanks for the patch! However, this issue is closed and the original patch is already committed. Can you create a new issue with a patch against the latest panopoly_wysiwyg? Thanks!
