* don't refetch remote ancestor statuses, improve descendant iter commenting

Signed-off-by: kim <grufwub@gmail.com>

* move collection page next logic so we capture first page of entities

Signed-off-by: kim <grufwub@gmail.com>

* improve log format argument quoting

Signed-off-by: kim <grufwub@gmail.com>

* improve code commenting of collection paging

Signed-off-by: kim <grufwub@gmail.com>

* only dereference announce's originating status if _not_ local. update DereferenceThread() signature. cleanup searchStatusByURI()
