Gateway on Arduino Mega 2560

@Yveaux I already did! https://github.com/mysensors/Arduino/pull/396

Feels much faster from here too!

Ok I got it to work. I misunderstood how the interrupts worked. Got it now. The culprit was the if statement detecting if the state changed. Since the state was being maintained while sleep, it wasn't firing when I pushed the button. Thanks for everyones help!!

@mfalkvidd Thanks, I'll try that.

Update and problem fixed! For everybody that will encouter this, the problem was at the sensor side because of the folder of the sensor! We created some metal brackets for it and they where exactly the same diameter. The fact that the mount squeezed the sensor made it return the lowest value. Just needed to adjust the hole and everything was ok!
