/**
 * Hook to register new Facebook OAuth actions.
 *
 * The Facebook OAuth module includes two default actions. The "connect" action
 * links a Facebook account with a Drupal user account. The "deauth" action
 * revokes Drupal's Facebook access for a user and deassociates the accounts.
 * You can write additional actions (such as data imports) by using this hook in
 * your own modules.
 *
 * A full example of implementing this hook is included with the README.txt file
 * included with the Facebook OAuth module.
 *
 * @return
 *   An array of Facebook OAuth actions keyed by a unique action name. Each
 *   action must specify at least the following properties:
 *   - title: A title for the action.
 *   - callback: The name of a function to execute after gaining access.
 *   - permissions: A list of Facebook permissions to request.
 *
 * @see fboauth_fboauth_actions().
