fix: Correcting spelling and formal errors

Description

Correcting spelling errors (according to Hunspell swiss german corrector in LibreOffice) and replacing phrases with corresponding words.

By the way: the link in the "_comment" is a dead link. I'm not sure if that was somewhat a living link in the past. You won't find it in the Wayback Machine (archive.org) either.
