support css -webkit- prefix

This adds and whitelists a bunch of css properties prefixed by -webkit-
based on what http://caniuse.com/#cats=CSS says.

I'm just enumerating the duplicate properties since it's not a large list,
and browsers are going to stop using -prefix- for new features.

unlikely that we will misinterpret a token due to a difference between the
vendor version and the speced version.

note also @-webkit-keyframes which is not expressible in the schema. I think
that's the only case.

CssSchema doesn't do double indirection, throws an error.
