HUGE Refactor - Here's a brief summary of what's happened:

* Refactored the compilation of the Coffeescript so it all bounces down into one lovely neat file
* Removed Zepto and replaced what it was actually used for with two lines of vanilla JS.
* Tap detection and scrore update logic now refined and doesn't cause a judder on iOS - largely thanks to getting rid of Zepto.
* IT NOW LOOKS ACE ON RETINA SCREENS
* Minor look/feel enhancements - still a ways to go
* General refactoring because things were getting VERY messy and certain classes were doing stuff that they should haven't been given the job of doing.

I think that's it. I'll have to keep on top of updating this thing as I go, huh?
