1.9.0

• Renamed the application from Smurftown to Battledeck.
• Added a proper app icon — an animated faceted gem mark in the header, plus a matching
  taskbar icon.
• Self-update works again for anyone still on 1.8.0 or an earlier, pre-rename install. Those
  copies look for Smurftown.exe inside the downloaded update and had started failing with "the
  package holds no Smurftown.exe" the moment a release stopped shipping a file by that name. This
  release carries the executable under both names once, so those installs update normally and move
  onto the current naming with everyone else.
