Correct Rasbian/Debian warning
We need to correct the "Rasbian is not Debian" warning on https://www.torproject.org/docs/debian.html.en. While this warning is technically true, tor will work perfectly fine on the newer Raspberry Pi 2 / 3, which uses the armhf, not armel like the Pi 1. Potentially this warning can put people off using tor on their Pi, which many people use to run relays.
Perhaps a better message would be:
"Rasbian is not Debian. Tor will run fine on the Raspberry Pi 2 / 3 but not the first generation Pi. This is due to the older armel architecture that the Pi 1 uses, where as the newer Pi 2 / 3 uses the armhf architecture"
