Remove unused
Feed update logging
Don't Subscribe on admin view
More logging for feed updates
Better feed update error levels

If the feed update date is future, that's an error, since we shouldn't be
trying to update it at all at that point, and suspect datastore
inconsistency. If the feed itself has no new data, that's not interesting,
so Info it.
Longer timeout on update
Log feed URL on no such entity
Don't try to update nothing
Yeah
Limit admin feed logs to the last 6 hours
Should be using pointers
Doc this function
Wait until the update is done to subscribe

The PUSH callbacks are happening faster than updates. Thus, the PUSH stuff
is saved to the datastore before the update is done. When the update
finishes, it squashes the new sub date with the old sub date (often zero).
Instead, make sure we've Put everything before asking to subscribe.
Limit incoming feed size to 2MB

This should prevent huge feeds from crashing instances due to memory use.
For example, the feed at http://www.rackspace.com is huge. Previously, it
would crash the instance, not allowing it to increment the error counter,
so it would attempt to update every 2 minutes. Now it should slow down.
Stop requiring certain namespaces in atom feeds

This fixes feeds that use the purl namespace, but work just fine.
Delete bad favicon blobs

These are things that the image server doesn't recognize.
Some sane request limits
Default to HTTPS
Ignore stories with no ID
