admin/project menu item is broken

Currently we have this:

  if (!module_exists('project')) {
    $items['admin/project'] = array(
      'title' => 'Project administration',
      'description' => 'Administrative interface for project management and related modules.',
      'page callback' => 'system_admin_menu_block_page',
      'access arguments' => array($admin_access),
      'type' => MENU_NORMAL_ITEM,
    );
  }

However, going to project/settings results in a WSOD because we're not telling the menu system where it can find the function system_admin_menu_block_page(). Attached fixes this.
