CSS and JS Refactoring

I removed the CSS keyframe animation "CCW" and added the standard "CW" animation and played it in reverse order.

Also change the JS to the toggleClass() method instead of using both addClass() and removeClass(). 

I also refactored the pulsing() function to use toggleClass() as well. That made the pulse class play in half time, though. So I changed the math to be 500ms instead of 1000ms. But hey, it got rid that weird 100ms offset! All in all it took the minified version from like 420 characters to 360 or so.
