Introspection

[gwynp]

I don't think POE has much of this.  I would like to get a list of all
current sessions (probably a list of IDs), then query for, with aliases
and current states.  Something like :

        @ids=$kernel->session_list();
        @events=$kernel->session_evnets($ids[0]);
        @aliases=$kernel->alias_list($ids[0]);  # does this currently work?
