- _ready() callback only happens once now, if you want to receive it again, use request_ready()

- C++ Nodes mostly do an internal process callback, so it does not conflict with users willing to use their own process callbacks
- callbacks such as _input, _process, _fixed_process _unhandled_input, _unhandled_key_input do not requiere calling a function to enable them. They are enabled automatically if found on the script.
