One Copyright Update to rule them all
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.

It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).

We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).

Also fixed "cf." Frenchism - it's meant as "refer to / see".

clayjohn 8fa76a5272 Move debanding into internal sky shader code so that it is applied after everything else.
This ensures that the debanding does not scale with exposure or any other effect.

clayjohn 385ee5c70b Implement Physical Light Units as an optional setting.
This allows light sources to be specified in physical light units in addition to the regular energy multiplier. In order to avoid loss of precision at high values, brightness values are premultiplied by an exposure normalization value.

In support of Physical Light Units this PR also renames CameraEffects to CameraAttributes.

Add dithering to ProceduralSkyMaterial to combat banding
Dithering was already present in PhysicalSkyMaterial. This brings
it to ProceduralSkyMaterial as well, with the same algorithm
and default intensity.

Default PanoramaSkyMaterial texture to black instead of white

Add sky cover texture for ProceduralSkyMaterial
This brings PhysicalSkyMaterial's Night Sky functionality to
ProceduralSkyMaterial, but in a more powerful and general fashion.

This can be used to display stars at night, or clouds at day and night.
For clouds, it won't be physically accurate, but it can look good still.

The Sky Cover Modulate property can be used to adjust the sky cover's
colors and opacity in real-time, which is useful for day/night or weather
transitions.

Tweak default ProceduralSkyMaterial and PhysicalSkyMaterial appearance
- Tweak colors to be less saturated and more balanced (in terms of hue).
  The cool blue sky is balanced by a warm brown ground,
  which makes reflections look closer to how they'd look like when using
  an HDRI panorama texture.
- Make the ground color dark on both ProceduralSkyMaterial and
  PhysicalSkyMaterial to reduce indoor light leaking, especially
  when using GI.
- Tweak the PhysicalSkyMaterial colors to be as close as possible
  to ProceduralSkyMaterial (with the default sun orientation).
- Tweak editor environment defaults to be identical to the default
  ProceduralSkyMaterial colors. Previously, the default editor sky
  color was different from the colors of a newly created
  ProceduralSkyMaterial resource.

Both new skies were tested without GI, with SDFGI and with VoxelGI.
They were tuned to look best when using ACES tonemapping with a
whitepoint set to 6, but they still look good with other
tonemapping operators.

Add a comment at the top of generated shaders
This comment is useful to determine the origin of ShaderMaterials
converted from built-in material types (such as CanvasItemMaterial
or StandardMaterial3D).

The Godot version is also included in case the shader needs to be
regenerated with a newer engine version.

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 🎆

Rémi Verschelde 07bc4e2f96 Style: Enforce separation line between function definitions
I couldn't find a tool that enforces it, so I went the manual route:
```
find -name "thirdparty" -prune \
  -o -name "*.cpp" -o -name "*.h" -o -name "*.m" -o -name "*.mm" \
  -o -name "*.glsl" > files
perl -0777 -pi -e 's/\n}\n([^#])/\n}\n\n\1/g' $(cat files)
misc/scripts/fix_style.sh -c
```

This adds a newline after all `}` on the first column, unless they
are followed by `#` (typically `#endif`). This leads to having lots
of places with two lines between function/class definitions, but
clang-format then fixes it as we enforce max one line of separation.

This doesn't fix potential occurrences of function definitions which
are indented (e.g. for a helper class defined in a .cpp), but it's
better than nothing. Also can't be made to run easily on CI/hooks so
we'll have to be careful with new code.

Part of #33027.

Rémi Verschelde 0be6d925dc Style: clang-format: Disable KeepEmptyLinesAtTheStartOfBlocks
Which means that reduz' beloved style which we all became used to
will now be changed automatically to remove the first empty line.

This makes us lean closer to 1TBS (the one true brace style) instead
of hybridating it with some Allman-inspired spacing.

There's still the case of braces around single-statement blocks that
needs to be addressed (but clang-format can't help with that, but
clang-tidy may if we agree about it).

Part of #33027.
