Title: Tweaking ycdn rules

Ive added some hostname matches which i think are widely used all over the internets.

Also matching the presence of header "X-Amz-Cf-Id" to confirm CDN usage. Thats something exclusively used by CloudFront.

One thing that can be considered is to match "sffe" in server header. It seems to be used by Google's static server, and all their static resources are self CDNed. This would then match the bulk of advertising related things currently reported by yslow as offender for ycdn rules.
