Standardization of import order

[Franjoo]

Since prettier typically ignores the order of import statements, we run into merge conflicts if some developers are using IntelliJ based IDEs, which handle import order automatically and others VSCode, which does not (out of the box).

VSCode users can configure similar behaviour in settings json with
"editor.codeActionsOnSave": { "source.organizeImports": true }

For an IDE independent solution, we could use prettier-plugin-organize-imports.

I opened a PR for that change, but since this will cause changes in almost every file, we should make sure that every other PR is merged before a project wide run-through of the organize-imports plugin.
