ConfigurO 2.7

Fixes

• Korean and other non-Latin languages could display as empty boxes. The list of
  fonts tried for each script was too short: the faces Windows prefers arrive
  with optional language features, and a machine without them had nothing left
  to fall back to. Every script now falls through to a widely available face.
• When no font on the machine can draw a script, the log says so instead of the
  text silently becoming boxes.
