MQTT backend for improved stability

The interface BLE<>LED is now implemented in MQTT. Two backend and one LED frontend services running... Still a hack, but seems more stable than the DBUS based previous version. In particular an encoding issue with messed up packages has been re-worked.

Reworked systemd services

Works perfectly without resetting.

Installation must be done manually using the scripts in ./install. Make sure to delete all previous com.moonboard.service and moonboard.service in all locations (i.e. using find / -name "com.moonboard.service" and find / -name "moonboard.service").

Working setup

This is a current working setup in my environment. The installation is done using:

• /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/8cH9azbsFifZ/moonboard/master/install/install.sh)"
  Once installed the DBUS service must be restarted (on every reboot) using this workaround:
• ssh -lpi raspi-moonboard ./moonboard/scripts/fix_startup.sh

Version running in GZ setup

This version is currently running in my "production" setup.
