Add info how to get logs from failing services

[s-martin]

We should add some hints how users can obtain logging info, if a service does not work.

I.e. we should provide some details how to use journalctl, so more info about failing services can be provided in the bug reports.

Maybe we should add the info to the bug report template.

Example #779.

We do have a script that collects information: /home/pi/RPi-Jukebox-RFID/scripts/helperscripts/Analytics_AfterInstallScript.sh

Does it make sense to enhance this with some journalctl commands?
