LanguageTool Support for Xwiki

https://languagetool.org/ is a multi lingual web service based text checking and correction tool, which also perform grammar and style checks.

It's core is OpenSource and it can be self hosted, even though I've not tried it yet and don't know how complete / usable a self hosted OSS variant actually is.

In any case, an Xwiki integration for LanguageTool could be interesting for corporate users.
