Original solitaire code

From http://mrdoob.com/lab/javascript/effects/solitaire/
Made to derp

* Change JS to handle our size/qty of derps
* Change BASE64 img to bigderp.png (from solitaire)
* Included png & psd for derp images
* Updated README
Overhauled to modular system

It was a PITA to deal with the "one monolithic image" system, so now
broken into a more modular system. Now you can add/remove base64'd
images as you like ( http://www.base64-image.de/ works well)

* Change to random image selection
* Added some debugging console.log's
* Added some code comments for others who want to play with this
* Have 8 BASE64'd derps
Adding the images to go with last commit
