merged SH1106 1.3" Display, thx @dAjaY85

added SH1106 to automatic build
added IP address to MQTT (version, device and IP are retained and only transmitted once after boot) #556
added `set_power_limit` acknowledge MQTT publish #553
changed: version, device name are only published via MQTT once after boot
added `Login` to menu if admin password is set #554
added `development` to second changelog link in `index.html` #543
added interval for MQTT (as option). With this settings MQTT live data is published in a fixed timing (only if inverter is available) #542, #523
added MQTT `comm_disabled` #529
