Shell-style programming in Kawa

[Per Bothner]

I checked in some semi-experimental code for Shell-style programming,
and specifically running processes.  Please play with it and let me
know how it works.  I have only tested it on Fedora Linux.

It's an unusual design for a "process API", and I think it's neat.
A write-up and "how-to" is in this (draft) blog article:

Please me know if that is unclear, incomplete, or has mistakes.
