[ccan] The JSAN gets rebooted

[Adam Kennedy]

Hi gang

Just a quite not to let you know that the JavaScript Archive Network
has been struggling back to life after a long sleep (caused by
problems with leadership and control of the servers).

As part of this, I've been putting together a new client. This time
around I've built it with a number of reusable pieces I've been
accumulating over the last couple of years specifically designed for
building fairly lightweight CXAN clients.

The good news is that this is working pretty well, we completed the
client libraries themselves in less than a week, and I'm putting the
finishing touches on the shell front end now.

With another few weeks of polishing and documentation time, most of
the parts should be pretty much validated, and ready for reuse on a
second-generation non-bzr CCAN, should you want to head in that
direction.
