Allow usage of coffee-script

[thibaut-sticky]

Hi,

I use coffee-script to write all my tests. Mocha by default is able to read coffee but it's not the case when you use it programmaticaly (new Mocha…).

For the moment, I have to run a first task to compile my code JS and then call grunt-webdriver. When error happened… line number target of course the JS file.

It could be a nice improvement to create a require option like this Grunt task

Do you think is feasable?

I test adding require('coffee-script/register'); into webdriver.js and it did the job.

Finally just adding require('coffee-script/register'); in my Gruntfile was enough.

Great! I will paste it into the README.
