NEW: HF MFU SETUID - set UID to a magic UL / UL-C tag. *not implemented* CHG: minor alignment for "Hf list" output. CHG: removed unneeded function parameters to the ultralight commands CHG: the const MAX_MIFARE_FRAME_SIZE is changed to MAX_FRAME_SIZE in the ultralight commands since the UL-Ev1 can have bigger frames than 18bytes. CHG: adding DES support for the Ultralight-c read commands on deviceside.
