Remove dependency on JCoffeeScript

[halfbaked]

Hi Edvinas,

I have made a lot of changes. It suited me, but not sure how you feel about it. The changes were mainly prompted by my need to have a newer version of Rhino that was being used by JCoffeeScript.

I have stripped out all the Module stuff as I don't believe it to be required any more - or am I missing something?

Let me know what you think! Thanks for your time, Eamonn
