Freshdesk: assets and static\d need fix

From https-everywhere-rules:

To whom it may concern:

assets.freshdesk.com is hosted on S3 (s3.amazonaws.com/assets.freshdesk.com/)

staticNone..None are hosted on CloudFront (d3o14s01j0qbic.cloudfront.net)

These need to have rules added before the one that handles arbitrary subdomains. (That rule should probably have a comment saying "Clients have unique subdomains," to clarify what it is / is not intended to handle.)
