rend-spec.txt description of HS directory system is bogus

Section 1.4 of rend-spec.txt (now in the torspec repo) specifies which relays are chosen to store a hidden service descriptor so vaguely that the description is useless.

That section also contains a completely bogus sentence: "A participant only trusts its own routing list and never learns about routing information from other parties."

This section of the rendezvous spec should be corrected.
