* Testing branch

* Added ability (by define) to scale analog sensor, also with number of decimals (it was formerly zero)
Useful when running on batteries to check the battery voltage just 
adding the appropriate resistor

* Reverting DHTSensor.h file

* Trying again to revert DHTSensor.h

* Using macro DEBUG_MSG

* fix method types

* Works with many different ultrasonic sensor models: HC-SR04, SRF05,
  SRF06, DYP-ME007, JSN-SR04T & Parallax PING)))™.
* Built-in digital filter method ping_median() for easy error correction
  (use SONAR_ITERATIONS build flag to configure).
* Allows setting of a maximum distance where pings beyond that distance
  are read as no ping or clear (use SONAR_MAX_DISTANCE build flag).

Add button definitions to the travis02 and travis03
IR_BUTTON should be uint32_t to properly work with new macro
eepromRotate return value is not used

- Integrated Geiger Counter
- Adapted sensor.ino to read and publish values.
- Modified html to add local dose rate into web page.
- Tested with influxDB.
- Tested with MQTT.

So you can add more different PMS sensors.

new devices&sensors + some fixes

Add support for humidity correction
