CSS redux; removed calculated from & to values

I was able to remove alot of source file data; 0% & 100% keyframe steps can be reduced or [eleminated if they are resets](http://lea.verou.me/2012/12/animations-with-one-keyframe/).  The client will insert those reset values automatically.
Test: http://codepen.io/tomByrer/full/EejIp
The net result is smaller files (saving ~12.5k, 7.1k after minify).  The savings will grow exponentially as more animations are added.

I also made the formatting consistent.
This branch builds upon my [fixed CSS minifer](https://github.com/daneden/animate.css/pull/131), though here I only changed the /source folder, so they are not co-reliant.
