Bang Tutorial redux -- javascript promises

Hi all,

I've been knee deep in Waterken server code for a few months now,
making some changes to make it perform better and be easier to review.
Anyways, I've finally gotten back to the stage where the next version
is in a usable state, and so I've been working on the new Javascript
interface. This version follows the ADsafe conventions and uses a
different syntax. There's a test page / tutorial at:

https://vsci.hpl.hp.com/-/bang/#s=6ysjn2sjvwl35p

I'm looking for some testing and criticism of the Javascript API.

Bill Frantz has been talking about using this interface as a remote
shell for CapROS <http://www.capros.org/>. If so, this same API should
work cross-platform across the Waterken Server and CapROS.

Thanks,
--Tyler
