* New syntax is type safe. * New syntax allows for type safe virtuals in native extensions. * New syntax permits extremely fast calling. Note: Everything was replaced where possible except for `_gui_input` `_input` and `_unhandled_input`. These will require API rework on a separate PR as they work different than the rest of the functions. Added a new method flag METHOD_FLAG_OBJECT_CORE, used internally. Allows to not dump the core virtuals like `_notification` to the json API, since each language will implement those as it is best fits.
