Adding support for external javascript libraries.

[saolsen]

I was trying to add three.js so I could play with it from cljsfiddle. I tried adding it as a script tag in the html.

But got a 404 from

http://cljsfiddle.net/http//cdnjs.cloudflare.com/ajax/libs/three.js/r53/three.min.js

Supporting adding external js libraries, either arbitrarily like I was trying to or a select set of them you can pick from like jsfiddle does it would be nice.
