On Windows this allows to avoid having to change the owner of the window
after it has been created, which in rare circumstances may cause the
window to bug out.
DisplayServer methods that only have a cosmetic effect print a warning (instead
of an error). These warnings can be silenced in headless mode, as it's assumed
that the cosmetic effect is undesired in headless mode anyway (e.g. changing
mouse cursor shape).
This prevents spurious warnings from appearing when running the editor in
headless mode, e.g. on CI to export a project.
Methods that print an error will continue to do so, as their
returned value may not match expectations and have cascading consequences
on the project (e.g. clipboard data not being retrievable).

fixing crashes when using `--headless`.

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".
