Rudimentary CoffeeScript support.

[ezzatron]

As of 1.2, CouchDB has native CoffeeScript support. This PR adds basic support for CoffeeScript to couchdb-compile.

Thank you very much for this pull!

Two questions:

• why is this Rudimentary CoffeeScript support and what is needed to make it full?
• could you please have a look at the tests - why do they fail?

[ezzatron]

Sorry, I guess I was only running the compile tests locally. All tests now pass.

I suppose "rudimentary" is not entirely accurate. I wasn't super happy with my code, and figured you'd probably want to clean it up a bit before pulling, especially with regards to useIndex(), where I essentially just copy-pasted the existing function body inside itself to look for CoffeeScript module indexes. I just needed something that would get us by for now at my work, as this PR does.

To make it more solid, I would probably expect to see support for arbitrary languages, not just JS and CS, given that you can use just about any language with CouchDB (as long as you have the language server to support it).

Perhaps something in the options could add additional filename extensions to check for when looking for module indexes. That way you could probably support TypeScript, IcedCoffeeScript, etc. etc.

In any case, since CS support is now native in CouchDB, I felt that should probably just work out of the box here.

Hey @ezzatron I am so sorry, I totally forgot your pr and changed the code according to standard, which lead to thousand merge conflicts. Could I kindly ask you to rebase your branch?

[ezzatron]

@jo No worries, I can't tackle it right now, but I'll take a look a it soon.

[ezzatron]

Sorry it's been so long. I ended up writing my own similar library to tackle my use case better. If you're interested in the challenged I ran into while trying to use couchdb-compile, I wrote a little summary of the differences between the two libraries.
