I've overhauled the core components and rewritten (almost) everything in
coffeescript. API/Service submodules now contain Client classes that
provide methods for the simplest possible access to MWS functionality.
Due to the core changes, these changes will break any existing code.
However, I tried to keep things as close as possible.

Almost done with the newer FBA module, finally. Will get this branch
working well enough to replace main branch asap.

Updated just about everything and fixed any errors that were preventing
use of this branch. See the test folder for up to date samples.

the coffee script for them since I don't know coffee script and was only
using the .js files.

Bugfixed the feeds.js submit feed request.
Added Get My Price for SKU and ASIN to products.

Fix: MWS_ORDERS to MWS_FEEDS
