 *
 *
 * Should 'event' trigger this..
 *   -> eg. somebody makes a 'EDIT' on 'person'
 *   -> a watch exists for
 *        ontable=person,
 *        onid = -1 <<-- every entry..
 *        person_id -> who is goes to.
 *        event = CRUD (eg. shortcut for edit/create/delete)
 *        medium = "REVIEW" << eg. review needed..
 *        
 *
 *  if onid == 0 then it will monitor all changes to that table..
