Don't remove "%" from keyframe 0% directive

Hi!

First things first, thanks for this port! It's pretty cool to be able to embed the YUI Compressor inside a PHP project and don't rely on a third party program outside the app.

This port breaks CSS animations and transforms because it strips the unit of a value when this value is 0, i.e.:

transform: translateX(0px) rotate(0deg)

becomes...

transform:translateX(0) rotate(0)

I have no idea if this a valid syntax or not, but what I'm sure, is that the animations I'm using don't work anymore once compressed.

I attach a screenshot of a diff, left side official YUI CSS Compressor output, on the right side YUI Compressor PHP port.

Seems like this is happening here... I'll try to have a look.

Does this just break the transform property?

[jchatard]

No, it's the keyframe only, I've found this issue on YUI: yui/yuicompressor#80

Currently trying to implement the fix they've committed.

Already fixed in version 2.4.8-1

Thanks for reporting!
