Initial (working) stab at a commonjs module system

Looks great! Just have one comment, will approve right after!

FWIW I got a couple seg faults while playing around with require

---

Example:

folder structure output from tree

.
├── main.py
└── node_modules
    ├── a
    │   └── index.js
    └── b
        └── index.js

main.py

#!/usr/bin/env python3

import pythonmonkey as pm
require = pm.createRequire(__file__)

print(require("a"))

a/index.js

module.exports = require("b");

b/index.js

module.exports = "Hello from B";

Below is my output from running main.py

./main.py 
Segmentation fault (core dumped)

---

It would be awesome to get this working so we could have some simple npm packages working like the infamous is-odd which requires is-number for instance (but otherwise works fine in PM without this specific issue)

As far as I know, this branch is now ready to merge, except that it entrains PR37 and PR57, which aren't.

@wiwichips It's confirmed been fixed on the latest wes/module-system
