Add a top-level .editorconfig file to the repo, to make it easier to achieve formatting consistency

[gggeek]

Most IDEs nowadays support .editorconfig files, which specify things such as the project's preferred indentation style, line-ending character, white-space stripping and so on.

This makes it effortless for contributors to adopt the project's formatting style.

Atm there is one in the /app dir, but not in the root nor in other top-level directories.

This leads to f.e. uneven usage of line-ending character in the documentation files...

Sounds good to add this! Feel free to go ahead with a PR :)

OK.

Btw,

• should I go for 4-spaces indentation as default? Or are there places where tabs / 2-spaces are preferred?
• do you know of any file in the project which does need to be non-utf8 encoded?

yes, 4 spaces is the default for most files afaik. There are some files that use 2 spaces, for example some yaml files IIRC. Probably best to check the files manually...

• do you know of any file in the project which does need to be non-utf8 encoded?

utf8 should be fine for all files afaik.
