Subject: www: add endpoint to retrieve altid dumps

This ensures all our indexed data, including data from altid
searches (e.g. "gmane:$ARTNUM") is retrievable.

It uses a "POST" request to avoid wasting cycles when invoked by
crawlers, since it could potentially be several megabytes of
data not indexable by search engines.
