v1.44.0

Fixed

• The device reconnects to Wi-Fi on its own. It asked for the network once
  at startup and never again - so if the association failed at boot, or the
  access point dropped the device later, it stayed there with a lit screen,
  every printer red and no way back short of unplugging it. It now asks again
  after fifteen seconds and keeps asking. This is the most important fix in the
  release.

Changed

• The NFC Tester is a proper bench instrument. It reads in English whatever
  language the device is set to - it is used beside a reader log and a
  datasheet, and two people comparing the same spool have to see the same
  words. One field per row, in a fixed order, with a colour bar across the top
  and the raw chip pages behind a HEX Code button.
• A spool's readings stay on screen when you take the spool away. They used
  to clear the moment the chip left the reader, which is exactly when you want
  to read them.
• The colour bar shows two or three colours for bicolour and tricolour
  spools, decided by the spool's aspect rather than by the colour bytes -
  black is a real colour, and an unused slot is stored the same way.
• Colours are shown in hex, the main one with its alpha byte, and the page dump
  is set in a monospace face so it lines up in columns.
• Titles, menu rows and printer names are heavier and larger, and buttons
  are set in a size meant to be read at arm's length.
• The NFC Tester has an icon of its own instead of borrowing the Display row's
  sun, and the sun now matches the other icons' size.
