Package bitcoinjs-lib as a nodejs module (VERY hacky, but good enough for now)

#!/bin/bash
# Package bitcoinjs-lib as a nodejs module

# Install bitcoinjs first (`npm install bitcoinjs-lib`),
# than run this in your app's directory.

TARGET=lib/bitcoinjs-lib.js

# Wrap all of bitcoinjs-lib and its dependencies in an IIFE
# and export the Bitcoin, Crypto and BigInteger objects.
# (module is shadowed because bitcoinjs-lib partially
# attempts to identify and use it, which results in
# broken code)
