FIX: "hf list 7816", the s-blocks is now also printed.

FIX: iso14443b.c got some minor adjustments in the demod and codeas14443btag. Seems it works better for me.
I still have the problem with powerup of a 14b tag.  I need to run the "14b raw -c -p 05 00 08" a couple of times before I get an answer.
