Typo for node_revision in active section Views field handler

There are two typos in workbench_access_handler_field_section.inc:

    if ($view->base_table == 'node_revisions') {
      $this->additional_fields['nid'] = array('table' => 'node_revisions', 'field' => 'nid');
    }
    else {
      $this->additional_fields['nid'] = array('table' => 'node', 'field' => 'nid');
    }

It's been driving me mad looking for this bug. This causes the "My Workbench" and "My Edits" admin pages to show the following debug message:

'Handler workbench_access_handler_field_section tried to add additional_field nid but node could not be added!'

Patch follows.
