Add FastClick library

+ Add "FastClick" javascript library. Passes touch events smartly to
click events to speed up how fast a website feels. I've been mucking

and accounts for various browser bugs
- Remove all custom 'touchend' events. FastClick seems to handle
everything well for you
+ Velocity -> 1.0.0
+ Velocity UI -> 4.1.4
