cdn 7.x-2.2

Version 2.0 beta 1 had some severe bugs. It also took much too long for fixes provided by the community to get committed. My apologies for that. This release fixes all known bugs, and brings significant new features. Most importantly: we've now reached feature parity with the Drupal 6 version of this module!

Major new functionality:
- Far Future expiration support (port from Drupal 6 sponsored by ONE Agency!)
- Advanced Help support
- hook_cdn_blacklist(): modules can now blacklist files that should not be served from a CDN

Changes since 7.x-2.0-beta1:

• Follow-up patch for #1413162: only call theme('advanced_help_topic', …) when Advanced Help is enabled.
