Platformio integration (#424)

* adaptation of structure to platformio

* also remove zgatewayRF315 (not usefull)

* replace boolean by bool

+  OpenMQTTGateway Addon  - 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
+ 
+    GPIO KeyCode derived from  GPIO Input
+
+    This reads up to 4 gpio with latch signal (gpio line) and combines the bits as KeyKode - can be connected
+    to EV1527 receiver.
