ADD: added a HF MFU INFO commmand, where you can see some tag info. Used to be in the readcard command. FIX: minor code clean up for ultralight & desfire commands in armsrc/mifarecmd.c, armsrc/mifaredesfire.c, armsrc/mifareutil.c CHG: Lowered the default MF_DBGLEVEL, it set to MF_DBG_ERROR. CHG: lowered a testing value for timeout in cmdhf14a.c
