I just merged @marshmellow's branch "iclass" and that was a lot of new functionality. *great work*

Things like the ICLASS, tryDecryptWord,

--
My other stuff like default keys, some new Mifare EV1 commands 0x40, 0x43 for the logging annotation,  start of the T55x7 configblock helper functionality (ripped from Adam Lauries RFIdler code)
Changes to the PCF7931 functions written,  which has a lousy input check..
