* Changed library to call by reference instead of using pointers. Makes code much cleaner.
* RelayNodes renamed to RepeaterNode to distiguish this from RelayActuator.
* Ack is now possible to request for all message types. Added ack-flag for some of the exposed internal messages and presentation message.
RF24 moved to utility folder of library. This results in one less include in sketches!
Serial flush in sleep method also means one less code in examples.
Removed set(bool) in message. Not needed. getBool just calls getInt
__attribute__((packed)) for RPI compability
Print more info in send/read debug prints.
Get internalTemp returns full degrees and uses longer Vref delay
Fix debug print gateway prepend (wrong command/type)
Fixed problem in RelayWithButton example. Now working with ack in both directions.
Serial protocol changed (incoming serial message have an new ack-parameter)
