Unify utf8 file encoding and code style settings (ical-org#632)

* Unify utf8 file encoding and code style settings

* No changes in code logic
* Store files with utf8 encoding (set with .gitattributes, rewrite existing files)
* Update .editorconfig and apply rules

* Update solution to file-scoped namespace
