Add a list of Javascript packages that just work out of the box.

@sadruddin if you'd like to contribute to this that would be awesome!

I don't think this is really necessary. What works or doesn't really depends on the interface exposed by the various components of a library, and trying to explain what does and doesn't work will likely be fairly subtle. Trying to explain the limitations of the system so that users can determine what won't work and why will be much more effective than trying to enumerate everything.
