Autocompletion based on "list" method
One can send a request like {"jsonrpc":"2.0","method":"list","params":["eb3bd8e7beb01338b21533a89b678971","*"],"id":0}
and get a response back listing all available calls and params. This in conjunction with ACLs returned when authenticating can be used to generate autocompletion automatically.
