Tangle - cookie keys file

The K includes the length.  There are actually 3 algorithms that can be used 
on the wire or to make cookies.  The wire has a slot for which algorithm to 
use.  The internal API is to pass the same routine different key lengths.

You need that even if you aren't in ratchet mode.  Consider a system that gets 
rebooted.  How does ntpd know if it should switch to a new K now or in 24 
hours?


> I don't think any cookie should ever touch the file system.

Ahhh...

There is actually a paragraph in the draft that suggests saving a cookie on 
disk so you can get restarted without having to do the KE dance.  I think it's 
marked SHOULD.  There aren't any helpful comments about how to figure out when 
to save a new cookie.

That's on the back burner for now.
