CHG: some magic generation1 tags is not following protocol and answers to the "halt" command. This gives an error and makes the users think something went wrong. This also affected the magic identification in "Hf 14a reader" command, where it in those moments stated "NO" even if the tag is indeed a generation1.

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..

A lot of changes...
.. ntag simulation stuff from @marshmellows branch "ntag/sim"
.. hf mf mifare fixes from @pwpivi.
.. hw status command
.. speedtest function from @pwpivi
.. Viking Functionalities, (not a proper DEMOD, but a start)
.. GetCountUS better precision from @pwpivi
.. bin2hex, hex2bin from @holiman
...
starting with getting the T55x7 CONFIGURATION_BLOCK for different clone situations. Ripped from Adam Lauries RFidler, nothing working or finished..
...
Started working with the T55x7 read command with password actually performs a write block... See Issue #136 https://github.com/Proxmark/proxmark3/issues/136 Not solved yet.
FIX: A old bug regarding: CMD_DOWNLOADED_RAW_ADC_SAMPLES_125K command, where it causes the USB_COMMAND_BUFFER to overfill is corrected. The message: "WARNING: Command buffer about to overwrite command! This needs to be fixed!" was showing when it happens.
The solution is not to add the CMD_DOWNLOADED_RAW_ADC_SAMPLES_125K to the storeCommand function.
MOD:: reverse back changes to 14443b.c
ADD: the hid-flasher/usb_cmd.h wasn't up to date with how it's other file /common/usb_cmd.h looks like.

-hitag2, -legicrf, HIDdemodFSK, CmDAWIDdemodFSK, CmdEM410xdemod, CmdIOdemodFSK
It should enable them to be aborted with a call to "hw ping / hw status" instead of only button-press. Which is good when you are scripting stuff.
