   multiple developers, as each time a developer gets an Activity Seen,
   they can update their state to use the Activity Entered that it points
   to.

-  Do include it in the data that gets signed, so it can be recovered
-  by trying each likely (recently seen) Activity as the prevMessage, and
-  checking the signature.
-  (If doing this, might as well switch to SHA512, since hash size does not
-  matter.)
 * loadLog should verify the hashes (and signatures) in the log, and
   refuse to use logs that are not valid proofs of a session.
   (--replay and --graphvis need this; server's use of loadLog does not)
