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
+ 
+   This is the Light Meter Addon based on modules with a TSL2561:
+   - Measures ambient Light Intensity in Lux (lx), Foot Candela (ftcd) and Watt/m^2 (wattsm2)
+   - Required Hardware Module: TSL2561 (for instance Banggood.com product ID 1129550)
+   - Dependencies: Adafruit_TSL2561 and Adafruit_Sensor
+
+   Connection Scheme:
+   --------------------
+
+   TSL2561------> Arduino Uno ----------> ESP8266
+   ==============================================
+   Vcc ---------> 3.3V -----------------> 3.3V
+   GND ---------> GND ------------------> GND
+   SCL ---------> Pin A5 ---------------> D1
+   SDA ---------> Pin A4 ---------------> D2
+   ADD ---------> N/C (Not Connected) --> N/C (Not Connected)
