v1.4.0

• The extractor now unpacks textures too. SCS archives store textures
  (.tobj/.dds) with their pixel data GDeflate-compressed and the DDS header
  stripped, which the extractor used to skip - base.scs lost about a fifth of
  its files. It now ships its own GDeflate decompressor and rebuilds a real
  .dds for every packed texture, so an extract is complete (models, defs,
  materials and textures).
• Mods using the 1.48 dlc_<name>/ layout are recognised. Building on the
  1.3.6 base/ support, content under a dlc_<name>/ folder is now read when
  the matching game DLC is owned, so such mods (e.g. the PGRS Scania pack) are
  checked for conflicts, maps and physics. Buying a DLC re-scans automatically.
• A third "frequently shared" conflict tier. Files touched by many mods at
  once (physics.sii, climate ...) used to be hidden; they now show as a neutral
  grey marker with a count - informative, never an alarm - so nothing is
  silently dropped. Resolves the physics.sii report (#42).
• Windows auto-update now restarts into the new version. The update could
  download but not swap itself in on Windows; it now hands off to the helper
  and restarts cleanly. AppImage was unaffected.
• Thanks to LLBBC (#42/#43/#47).
