Remove some old hosts for actblue.com

Hi, admin for ActBlue here. I noticed your rules for our site referred to some CDNs and S3 buckets that are no longer used. I have attempted to clean them up and simplify the redirects. I have also added m.actblue.com to redirects (our servers do this redirect -- there used to be a different URLs for mobile).

Please let me know if I need to sign any CLA or if this needs improvement. Thanks.
