convert library/namespacing to CommonJS about bbop-js

A slightly hybrid style seems to work (contrib/commonjs), but given the amount of interconnectedness at the core, will have to commit more fully to work it out. Branch for "issue20".
This will necessarily change the testing and inclusion workflows a bit, but should greatly simplify scripting and cross-platform usability.

Pretty much done and pushed. Still looking at some of the console script examples.

A little public explanation for the way I did it from my notes:
---
just to clarify the rational for:
var bbop = require('bbop').bbop;
instead of the more common (and correct?)
var bbop = require('bbop');
1) if bundle bbop.js in with amigo.js, we could then have:
var bbop = require('amigo').bbop;
or something
2) more importantly, the exports assumption in the typical server/common environment
would want us to write our code like
---
exports.core.chop = function(x,y,z){ ... };
...
return exports;
...
---
that would allow us to do it the expected way on the server,
but it would introduce a lot of browser-side issues with
namespaces when it came to amigo and bbop playing together, etc.
and more overhead in dealing with that (external libs, etc.)
so we have a hybrid solution which should technically be
commonjs modules 1.0, but still tries to behave like normal
browser JS. This is only possible because we build single files
instead of having interdependent modules in different files

Appropriate changes made to the amigo JS libraries as well.

The server side stuff has proved to work a lot more sensibly, and node no longer needs a wrapper runner to create the environment. Done then (although a lot of the scripts will remain borked until I freshen them at some point).
