* This function determines the actions of the members passed in urls.

* Adding actions to this list is actually relatively easy...
* - for actions anyone should be able to see, just add a string named whoall_ACTION.
* (where ACTION is the action used in index.php.)
* - for actions that have a subaction which should be represented differently, use whoall_ACTION_SUBACTION.
* - for actions that include a topic, and should be restricted, use whotopic_ACTION.
* - for actions that use a message, by msg or quote, use whopost_ACTION.
* - for administrator-only actions, use whoadmin_ACTION.
* - for actions that should be viewable only with certain permissions, use whoallow_ACTION and
* add a list of possible permissions to the $allowedActions array, using ACTION as the key.
*
* @param mixed[]|string $urls a single url (string) or an array of arrays, each inner array being (serialized request data, id_member)
* @param string|false $preferred_prefix = false
* @return mixed[]|string an array of descriptions if you passed an array, otherwise the string describing their current location.
