better documentation for "Clients must be authorized to join private or presence channels.

[alexanderadam]

Currently we're running into the Clients must be authorized to join private or presence channels. exception in our Rails application.

The message is linking to the authorizing users documentation, which is great. 👍

However, can you clarify in the documentation whether Pusher will (re-)tackle these cases (i.e. whether a retry will happen).

Right now we assume that the exception message might be misleading when connection issues appear so it would surely be helpful if the docs would help.

PS: Furthermore the This authenticates every user. Don't do this in production! comment is used inconsistently.

In the top examples of the documentation all of them contain the warning and if you're landing directly at the JSONP examples it is missing and people might not see this.
