      Update CardReader schematic · a9f9514e

      Connect ISP Header pins 4,6,8 to GND.
      Leave AREF floating. We don't use the ADC anyway and routing that thing on the board is difficult.

      Rework of card reader protocol and code. It now uses a generic transport protocol with error checking (CRC16).
      Rework card reader interface, it now drives the LCD and card remotely.
      Switch key storage to external EEPROM.
      Cache only the first 4 byte of key hashes in RAM, not the full hash.
      Replace old single char commands with a management CLI. Currently a hardcoded login is used. This is subject to change.
      Use an external hardware RNG for random numbers. Thanks to StuC for building this nice piece of Hardware.
      Disable power save modes for now.
      Enable Brown out detection to avoid accidental door commands on power fail
      Update schematics.
