CoffeeScript version of the time span formatter between now and the date specified in a "Facebook way"

Earlier I published an ActionScript utility method that allows you to format the time span between now and the date specified in a "Facebook way".

Now I port it to CoffeeScript.

You can notice that the code is very similar, but thanks to CoffeeScript native string interpolation it is shorter and easier to read and understand!
