 * Function name: block_action
 * Description:   Called to see if this room wants to prevent a living
 *                inside from performing an action.  This will be called
 *                once for each target.
 * Arguments:     string cmd - the command name
 *                object actor - the actor
 *                object target - the target of the action
 *                int cmd_attrs - the command's attributes (from cmdparse.h)
 * Returns:       0 - Command allowed
 *                1 - Command blocked without a failure message
 *                string - Command blocked, use return value as failure message
