Document one more item in documentation for uninstalling

[Yann R]

Trying to fully clean up the Serviio preferences from my macOS system, I noticed that the documented items to be removed are not complete:

sudo rm -rf /Library/Application\ Support/Serviio
sudo rm /Library/LaunchDaemons/org.serviio.server.plist

It seems that the user must also do rm -rf ~/Library/Application\ Support/Serviio-Console-Wrapper, for instance to clear the connected/authorized device list.

Regards.
