change source path for loading facebook javascript

Hi,
I am not sure how best to submit this question and possibly bug since I don't see the steroids addons js in its own repo.  I am sending this request with the understanding that you should probably patch this in source.

I noticed a couple traces from my app when I included the addons, it appears that the path to load these JS files isn't correct.  Can you take a look?

Also, it is named steroids.addons.js here (and in various examples) but the latest version that I have is actually just index.js included in the package.  It might be helpful to update the examples, docs, and anywhere else.
