Moved Stats box styling from javascript to <style> block. Updated URIs to moved Controls objects

   *Used style block instead of seperate CSS file to reduce the number
of GETs required
   * Also removed old PointerLockControls
Refactored controller selection code
Controls base class and subclass PointerLockControls in CoffeeScript

**note:** compile coffeescript with `coffee -b -o lib/js -c lib/coffee`
