* 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

So you can add more different PMS sensors.

And found DEBUG_MSG could not be used in the sensors header file.

1. Support PMS5003T/PMS5003ST;
2. Replace data reading method;
3. Remove PMS library dependency;
4. Support smart sleeping mode to extend the sensor’s lifetime.

Isolated dependencies

sensors dependencies

enums, macros and prototypes.

I2C dependencies moved to actual sensor files.

definitelly redefine

new devices&sensors + some fixes

* images for the devices
* optimized images
* fixed typo in ech1560
