using 'tap click' instead of 'click' events & more ...

On android 'click' events (with or without fastclick) fire way to often (specially if it glitches just a tiny bit while scrolling) and this results in the great annoyance of opening links you scroll over.

The best solution is to start using the 'tap' event instead of 'click' for interactions, however the 'click' events are still firing shortly after the 'tap' event, so I added zepto.ghostclick.js to ease this.

I also removed FastClick, if we're using 'tap' we shouldn't need it anymore.

This should be tested thoroughly I think, because idk how it responds on iOS devices ...
