Render array for action links

[soniktrooth]

menu_local_actions is being rendered with a theme function. A render array makes it adjustable by subthemes.

Out with :

    $variables['tabs']['#primary'][]['#markup'] = theme('menu_local_actions', array('menu_actions' => $variables['action_links'], 'attributes' => $dropdown_attributes));

In with :

    $variables['tabs']['#primary'][] = array(
      '#theme' => 'menu_local_actions',
      '#menu_actions' => $variables['action_links'],
      '#attributes' => $dropdown_attributes,
    );
