Title: Fix validation of background-position

Current version of `background-position` validator doesn't match W3C CSS3 spec.

This update fixes that, but does have one side effect: In some cases, in can output different error messages than it does now (see the output for `left center right`).

I don't like the `count` variable, but the version without it was more verbose and less clear to me.
