Title: Add support for vendor prefix in CSS keyframes

Hi!

I'm using CSSTidy in one of my projects and I just realized that the keyframes declarations in my CSS file were deleted by the optimization.
I found out that it was because I was using `@-moz-keyframes...` instead of `@keyframes...` which works good with the optimization.

As `@keyframes...` doesn't work in Firefox for now, I modified CSSTidy to accept declarations like `@-moz-keyframes...`.
I also did the same for other prefixes : `-o`, `-webkit` and `-ms`.

It seems to work, and I hope it was the right way to solve the problem.
