webcredits v 0.1 released

I've released v 0.1 of webcredits

Webcredits is a simple accounting system based on a ledger which can
trigger secure payments via an HTTP server, command line or javascript API

javascript : https://www.npmjs.com/package/webcredits
source : https://github.com/webcredits/webcredits
homepage : https://webcredits.org/
spec: https://www.w3.org/community/webpayments/wiki/Web_Credits

It's still probably pre alpha stage (v1.0 will be production) but ive
documented up quite a bit more.  And it is actually working

I've been testing this over a few years, and the major change now is that
it's secured for multi user over HTTP.

The design is for more interesting apps to be layered on top of the
accounting system, and I'll be hopefully showing some demos quite soon.
