Editorconfig

[kappsegla]

Since we are many people working on this project some of us might have there own personal settings for formatting of files. This might be problematic since files that are updated by several people might change just because of formatting rules.
We can create an .editorconfig file with common settings that will be applied automatically in all IDEs that support this when opening this project. https://editorconfig.org/

I suggest taking a look in project https://github.com/fungover/haze as inspiration. Some settings might be unnecessary since they might have a default value?
