New GDScript tokenizer and parser Sometimes to fix something you have to break it first. This get GDScript mostly working with the new tokenizer and parser but a lot of things isn't working yet. It compiles and it's usable, and that should be enough for now. Don't worry: other huge commits will come after this.

Update copyright statements to 2021 Happy new year to the wonderful Godot community! 2020 has been a tough year for most of us personally, but a good year for Godot development nonetheless with a huge amount of work done towards Godot 4.0 and great improvements backported to the long-lived 3.2 branch. We've had close to 400 contributors to engine code this year, authoring near 7,000 commit! (And that's only for the `master` branch and for the engine code, there's a lot more when counting docs, demos and other first-party repos.) Here's to a great year 2021 for all Godot users 🎆
