emonSD-17Oct19 release

Following on from the beta release of the EmonScripts automated emoncms build script. This image is the first pre built emonSD image release that uses the scripts for the full image build.

Feel free to build the image from scratch rather than download the image. This can be done using the automated build script, see: https://github.com/openenergymonitor/EmonScripts

Special thanks to @borpin for all his help and guidance throughout the development process and to @pb66 for helping early on with the log2ram configuration and logrotate approach.

The Build script works well on UbuntuLTS once the modules to be installed have been adjusted. There is also some work going on to use the script on a Pi ZeroW.

Awesome, been hanging for a chance to refresh the pi! Great job all involved (as always), will advise if I hit any snags over the next couple of days.
