Message:

Minor rework: Always fill td->log now and use it not just for show_ids, but
also for stream deduplication. Also, drop tweets from unknown people unless
fetch_mentions is set. The stream will feed us that spam either way but not
everyone wants to see it.

Last, fixing a bug where in streaming mode, per-user last tweet times were
no longer getting tracked.
