Add RedHen to admin menu

Thanks @nedjo. Know anyway to get this to make the admin menu section to expand? Currently just adds a root /redhen path with no child items.

Great patch @nedjo, commited.

Is there a reason we can't change the menu items to the url admin/redhen ? This way we would get ourselves an entry in the "Management" menu by default and not have the weirdness of building up a menu in navigation and then copying it?

Using this method there is no way for me to change the position of the redhen menu without patching the module.

The main reason is that changing the path to /admin/redhen will ruin the breadcrumb path for all items below /redhen. I'd prefer to leave as is.

RedHen is administration functionality - it messes up all sorts of bits of Drupal not being under /admin. A good example is that redhen does not use the admin theme.

For anyone else struggling with this, I found the following code helpful:

 /**
   * Implements hook_custom_theme().
   *
   * Make redhen pages use the admin theme rather than standard theme.
   */
  function mymodule_custom_theme() {
    if (arg(0) == 'redhen') {
      return variable_get('admin_theme', NULL);
    }
  }

Or even better, this hook properly describes the redhen paths as admin paths;

/**
   * Implements hook_admin_pages().
   *
   * Make redhen pages use the admin theme rather than standard theme.
   */
  function mymodule_admin_paths() {
  
    $paths = array(
      'redhen' => TRUE,
      'redhen/*' => TRUE,
    );
  
    return $paths;
  }
