Cache Busting: There doesn't seem to be any on the enqueued stylesheet url

[acketon]

I just checked a couple sites using custom.min.css and there doesn't seem to be any cache busting on the URL. Is that intentional? It seems like it isn't the behavior we would want as users would have to do a hard refresh to get the latest version of custom.min.css loaded. Should we add a file timestamp to the end of the url or some version number or revision number so it forces browsers to get a new copy?
