Hub should record feed IDs for arbitrary pings it has not seen in the last N days

[GoogleCodeExporter]

This further helps handle the aliasing problem by allowing the Hub to keep
a record of all feeds it's ever seen and how those feeds alias to real feed
URLs. This also decouples (amazing) the publisher's URL of choice from the
subscriber's URL of choice by having the presence of pinging act as a weird
kind of registration. For DoS protection we're going to need to enforce a
maximum number of feeds per domain and potentially a whitelist.

Due to the approaching shutdown of Google Code 
(http://google-opensource.blogspot.ch/2015/03/farewell-to-google-code.html) 
we're moving all public PubSubHubbub development to the pubsubhubbub 
organization on Github:

https://github.com/pubsubhubbub

The protocol spec resides under https://github.com/pubsubhubbub/PubSubHubbub 
while the various client libraries and example applications have separate 
repositories.

Wiki content has been migrated to the PubSubHubbub project as well:

https://github.com/pubsubhubbub/PubSubHubbub/wiki

Please re-open your issue on GitHub if it's still relevant.
