* `_gui_input`, `_input`, `_unhandled_input` and `_unhandled_key_input` are now regular C++ virutal functions. * Everything else converted to GDVIRTUAL * BIND_VMETHOD is gone, always use the new syntax from now on. Creating `_gui_input` method and using the binder to register events will no longer work, simply override the virtual function now.
