The comment argument is my addition, which allows comments to be
white space collapsed and unindented if passed the value "noindent".

css_summary is a function that is not provided a scope by the cleanCSS
function.  It is intended to be provided as a closure that it can access
the interiors of cleanCSS, but remain accessible outside cleanCSS.  This
function returns the number of HTTP requests from the beautified CSS and
what those requests are.
