Bugfixes:
- Byteorder was wrong when displaying ATQA in hf 14a read
- 7 Byte UIDs were truncated to 4 Bytes when displaying in hf 14a cuids
git housekeeping:
- added *.log files to .gitignore
- new file .gitattributes: tell git not to diff or merge binary *.bit (FPGA) files
hf 14a reader enhancement

In order to be able to distinguish between Mifare Classic and Mifare Plus
in Security Level 1 (SL1, Mifare Classic Compatibility Mode), hf 14a reader
now always tries RATS - even if SAK claims not to support ISO14443-4.
Merge branch 'master' of https://github.com/Proxmark/proxmark3
Bugfix hf 14a raw:
number of bits sent was wrong when option -c was used without option -b
minor bugfix and enhancement to hf 14a reader
- "SAK incorrectly claims ... " message was displayed incorrectly
- now decodes FSCI, SFGI, FWI and displays FSC, SFGT, FWT resp.
minor bugfixes to hf mf sniff and hf 14a snoop
- tracing was not always enabled when starting hf mf sniff or hf 14a snoop
- ATQA was displayed in wrong byte order in hf mf sniff
- 4 Byte UIDs were displayed as 7 Byte UIDs (padded with 0x000000) in hf mf sniff
- same for logfile names.
- assignment (=) had been used instead of == in comparisons (shouldn't have been relevant though)
bugfixes hf mf sim
- output of debug messages caused communication failures due to timing issues.
  hf mf dbg 4 now required to see these debug messages.
- changed help text for hf mf dbg
- fixed minor bugs in help texts for hf mf sim and hf mf ecset
- display "key A" or "key B" instead of "key=0" or "key=1 in hf mf sim
bugfix hf mf sim
- an additional erronous byte was sent after SAK
add *.eml to .gitignore
Various scripts from iceman
Some more lua-scripts and library fixes from iceman, including more default keys
fix/add support for 4K (and other non 1K) card sizes in hf mf commands
- hf mf rdsc (fix): didn't account for 16 block sectors, allowed max sector 63 instead of 39
- hf mf ecfill (add): added (optional) card size parameter and support for non 1K cards
- hf mf dump (add): added (optional) card size parameter and support for non 1K cards
- hf mf dump (fix): Access Condition 011 not handled correctly (tried to access with key A)
- hf mf restore (add): added (optional) card size parameter and support for non 1K cards
- hf mf nested (fix): didn't account for 16 block sectors, allowed max sector 63 instead of 39
- hf mf nested (fix): always dumped 16 keys to dumpkeys.bin instead of correct number
- hf mf chk (fix): always dumped 16 keys to dumpkeys.bin instead of correct number
- hf mf eget (fix): displayed three instead of one block
- hf mf eload (add): load 4K .eml files (but accepts 1K .eml files for backwards compatibility)
- hf mf esave (add): always save the whole emulator memory (4K) instead of 1K only
- hf mf ecfill (add): added (optional) card size parameter and support for non 1K cards
hf mf dump error handling, revive hf mf chk d option, provide known keys dictionary file
- hf mf dump: abort on unrecoverable errors. Don't create file dumpdata.bin in this case.
- hf mf chk: re-enabled and fixed option d (dump keys to dumpkeys.bin).
  if there are unknown keys, write 0xffffffffffff instead to the file.
- provide a default key dictionary file for hf mf chk (default_keys.dic). Contents taken from
  mf_default_keys.lua
hf mf dump bugfix: wrongly tried key A instead of key B for a specific Access Condition
