Subject: [PATCH 1/2] Add whisper to the top-level compat interface

* Otherwise when using compat, accessing whipsper is very awkward. ie, if you have "channel = this.consumer.subscriptions.create", you need to call "channel.channel.whisper"

* With this change, you can call "channel.whisper" instead
