Possibility to setup the interrupt_mode in sleepnode

Now it is possible to setup the interrupt mode in sleepnode (default 0=LOW)

if(INTERRUPT_MODE==0) attachInterrupt(interruptPin,wakeUp, LOW)
if(INTERRUPT_MODE==1) attachInterrupt(interruptPin,wakeUp, RISING)
if(INTERRUPT_MODE==2) attachInterrupt(interruptPin,wakeUp, FALLING)
if(INTERRUPT_MODE==3) attachInterrupt(interruptPin,wakeUp, CHANGE)
