Florian 68352f10e6 differentiate receiving and publishing mqtt for the new json option in user_config.h 
#318 so as to avoid user with non modified controllers to have regression on receiving (per default receiving is activated for both json and simple and prioritary analysed for json)

OpenMQTTGateway - ESP8266 or Arduino program for home automation
Act as a wifi or ethernet gateway between your 433mhz/infrared IR signal and a MQTT broker
Send and receiving command by MQTT
This program enables to:
- receive MQTT data from a topic and send RF 433Mhz signal corresponding to the received MQTT data
- publish MQTT data to a different topic related to received 433Mhz signal
- receive MQTT data from a topic and send IR signal corresponding to the received MQTT data
- publish MQTT data to a different topic related to received IR signal
- publish MQTT data to a different topic related to BLE devices rssi signal
