Instead of using a C++ wrapper, I used a Node version of CoffeeScript
with a small JS wrapper (src/modules/_coffee-script.js). This way, since
the module system is similar enough to the Node.js module system, I only
need to require CoffeeScript in bootstrap.js and all the support for
.coffee is added by CoffeeScript itself.
To include a newer version of CoffeeScript in the source tree, see
tools/import-coffee-script.sh.
