rewritten: sessions management

Browse Source 
(Session, SessionContainer, SessionManager)
           now a Session object don't copy all fields in its copy constructor (only id)
           the rest fields are set after the object is inserted in SessionContainer
added:     after successfully login a session id is changed
added:     plugin.Call() methods with a first argument a pointer to a Session object
