Pr/61 add I2C sensors BME280 and BH1750 (#64)

* changed user config

* added lightsensor module

* changed Pin Adresses

* Added I2C Lightsensor

Added the I2C Lightsensor and Switchted most Pins

* removed some debug to serial

removed some debug stuff was send to serial console

* Merge with Master

* Too much things for arduino uno

per default remove sensors for it

* Adding I2C Module function

Opens the Door on OpenMQTTGateway for "i2c Bus Modules/Sensors"

* Fixing BH1750 detection

Fixing the detection for a missing BH1750 Module

* Add libraries and define sensors depending on wiring type #63
