google webfinger prototype updates

Summary of changes:

* collapsed two host-meta Links into one, with two Rels.  (Dirk & Eran are still considering different aspects of this, so for now they're both there)

* removed the 'foo' type, as it was confusing people.  It was just supposed to be an example.

* expanded the FOAF a bit more.
