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".

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 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.
