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)
