Title: CSS_UriRewriter: do not rewrite about:blank

`background-image:url(about:blank)` is sometimes used as an IE hack. For example, http://stackoverflow.com/a/1664014/1215512. This patch disables Minify_CSS_UriRewriter from rewriting about:blank, which prevents unexpected HTTP requests to /prenpend_path/about:blank. Thanks.
