Add a new .editorconfig and reformat code (#76)

*I'll start working on features and bugfixes after this PR, I promise*
very short summary:
- no more braceless statements
- braces are on new lines now
- `sealed` on everything that can be `sealed`
- no more awkwardly looking alignment of fields/parameters
- no more `Service` suffix on service fields. yeah.
- no more `else`s. who needs them?
- code style is now enforced by CI
