* fix parity encryption (thanks to Eloff, http://www.proxmark.org/forum/viewtopic.php?id=6347)
* add support to simulate Mifare Mini, Mifare 2K and Mifare 4K
* change to standard LED handling (A: PM is working, B: reader is sending, C: tag is responding, D: HF field is on)
* NAK on unknown commands
* allow unencrypted HALT
* don't display messages during simulation (or we will miss next reader command)
* use DMA to receive reader command
* switch earlier from send to listen mode
* move ADC initializer to iso14443_setup
* remove remainders of incomplete Mifare 10Byte UID simulation
* show 'short' bytes (7Bits or 8Bits without parity) in 'hf list mf' and 'hf list 14a'
* whitespace
* detect and use RDV40 higher voltage ADC channel for hw tune, hf tune, hw detectreader
* fix mode switching in hw detectreader
* detect Smartcard Slot in hw version
* i2c changes from https://github.com/RfidResearchGroup/proxmark3
* some formatting in proxmark3.h
* more timing fixes
* correctly determine correction bit (taken from iceman's fork)
* add checking of Access Conditions for Read command
* never allow reading KeyA
* move to separate files mifaresim.[ch]
* check CRC of commands
* don't execute commands without successfull authentication
* ensure correct timing of REQA, WUPA, ANTICOL and SELECT responses
* trace reader commands immediately, only fix start time after tag response. Decreases time to be ready for next reader command.
* remove iso14443-4 remnants
* trace raw reader commands instead of decrypted ones
* some refactoring
* fix hf mf sim
* timing: decrease time to get ready for new reader commands
