fix syntax error during cake test

[brewingcode]

Coffeescript 1.7.1 broke the mocha test. Found this solution at:

mochajs/mocha@2f42a83

The exact error looks like this:

set app environment: development

/private/tmp/express-coffee/test/app_test.coffee:1
xports, require, module, __filename, __dirname) { request = require 'supertest
^^^^^^^^^^^

Errrr, this was changed 1.7.0, not 1.7.1. On reading the changelist for coffeescript, it's spelled out:

1.7.0 – JANUARY 28, 2014
When requiring CoffeeScript files in Node you must now explicitly register the compiler.
This can be done with require 'coffee-script/register' or CoffeeScript.register(). Also for
configuration such as Mocha's, use coffee-script/register.
