Website: Auto-detection of language (re-)activated

The option to automatically detect the text language has been offered on https://languagetool.org for quite some time. But for some reasons, the sub pages like LanguageTool - Grammatik-, Stil- und Rechtschreibprüfung never had this feature. Not sure why, so I have activated it again. If you have a good translation for “auto-detect” for your languages, please let me know.
