function fb_connect_translated_menu_link_alter in Drupal for Facebook 7.4

Implements hook_translated_menu_link_alter().

Customize the link on each page, to return the user to this page after connecting. Experimental use of '</a>...<a>' because drupal will surround our title with <a>...</a> and for our markup we don't want that.
