Updated Blockchain, New lite Image and Pi Zero Support
Changes:
- updated the blockchain to 2020-02-04 (now included as a standalone download, good for any version of the wallet)
- New lite image for those that want to run without the GUI overhead (use this for Pi Zero)
- Created wallet binaries specifically for the Pi Zero (no -qt available) to complement the standard binaries
Binaries for Pi2 and greater: /home/pi/btct/bin/{btct binaries}
Binaries for Pi Zero: /home/pi/btct/bin/pi-zero/{btct binaries}
