Development

* Node.js support added. 
* Tests added (both jasmine and crummy console.log-based for the browser testing)
* More structured and commented code is now in place, hopefully extensibility will see the benefit
* Performance seemingly unchanged
* Pomo.load(resource, options) signature changed for the 'link' mode from ```load('link_id', options)``` to ```load(null,options)``` because it will now go through every single <link> element that it sees fitting.
