Add "Script name casing" to Project settings editor/naming

[ghmart]

Describe the project you are working on

All projects using GDScript.

Describe the problem or limitation you are having in your project

When attaching new GDScript it will be automatically named after node name, which is usually capitalized.

Lower-cased filenames are recommended by official documentation's "Best practices" and different Godot tutorials to avoid problems on case-insensitive filesystems.

So the user is forced to manually make script's filename lower-cased. This is annoying.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Add "Script name casing" to Project settings editor/naming (defaulting to "snake_case"). That way it will be harder to accidentally create "Name.gd" when there is already "name.gd".

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

See above.

If this enhancement will not be used often, can it be worked around with a few lines of script?

Maybe some complicated EditorScript-extending script that will traverse and report unwanted filenames. I don't know.

Is there a reason why this should be core and not an add-on in the asset library?

This is a new project setting.
