Pretty hacky solution but it's better than an infinite loop.
All this import setup needs to be redone, it's very difficult to properly
bail out from an invalid import without triggering reimport loops.
Also fix underline not visible at default editor scale in LinkButton.
Fixes#73319.
This relaxes the naming restriction on fbx2gltf binaries,
as people may be renaming them then wondering why they've disappeared
from the dialog unless they select "All Files (*)" as a filter.
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".
* If FBX files are found, a dialog will pop up asking to configure FBX2glTF.
* Dialog can also be accessed by going Editor -> Configure FBX Import.
* The dialog also shows a link to click to download the converter, which
should contain instructions.
