Add .editorconfig

Hey!

Awesome app, judging by the screenshots, I'm looking forward to the version for Android, looks cool! 🍾

EditorConfig is a standardized opt-in way to help collaborators auto-set their editor on a per-project basis for various formatting options, e.g. spacing and tabs. Some editors (e.g. WebStorm) honor it out of the box; others (e.g. VSC) require installing a small extension. EditorConfig files also affect how code renders in certain engines, including GitHub's web interface.

Yep I can't wait to have that rolled out either #2, hoping within the next few weeks will have it launched!

Oh, can you do it, because then you will need a new pull request? I do not want to do it because of this.
