Library is broken in environment using CommonJS modules

Library is broken in CommonJS environment. Module is wrapped into anonymous function to provide something close to UMD module format:

(function(ns) {'use strict';
    // code
}(typeof module !== "undefined" ? module.exports : window));

It works perfectly in non-CommonJS environment, since it sets ns to Window. In CommonJS environment ns will be module exports object. But code of the library extensively uses ns variable to access Window’s properties: 1, 2, 3, etc. Obviously in CommonJS environment these properties are undefined, so it fails/behaves very weird (in my case animation went insane, because ns.performance was undefined and it used Date.now() to get animation start time (and they are completely different things).

The simple solution would be just removing ns. prefix from all the global variables. If you think we should go with this solution, I can prepare PR.

Check out updated example to get simple reproduction of the issue in CommonJS environment.

As a side note. I find the Regex based build process a bit speculative. Any reason why you use that instead something like this babel plugin for example? Maybe we can improve build process as well?
