Add more commonly used libraries to the whitelist (bug 1086562)

https://bugzilla.mozilla.org/show_bug.cgi?id=1086562

I would have liked to add enyo.js and cordova.js but they don't seem to release prebuilt .js files directly, and I'm not sure how they are included in the wild. /cc @eviljeff who might know some apps which would use those that I can look at.
mmm I had not thought of this, yeah I see how it could be bad. I added this because the package I was testing with (which is a real app someone uploaded) is gigantic and made of several independent modules with some files repeated multiple times. But it shouldn't be a common use case, I'll remove this.
