[Health] Raspi Image for GNU Health 3.6

[Axel Braun]

All,

just in case you need to burn some time over the holidays, here is an idea for
this: The GNU Health 3.6 Image for the Raspi 3, based on openSUSE Leap 15.1,
the LXQT Desktop and the demo-database preinstalled.

Until we found a place on the official (download) server, please follow
instructions here:

Have a good xmas and a happy new year
