Update to v106r26 release.

byuu says:

Changelog:

  - nall: added -static-libgcc -static-libstdc++ to Windows/GCC link
    flags
  - bsnes, higan: added program icons to main window when game isn't
    loaded
  - bsnes: improved recent games menu sorting
  - bsnes: fixed multi-game recent game loading on Windows
  - bsnes: completed path override support
  - bsnes, higan: added screensaver suppression on Windows
  - icarus: add 32K volatile RAM to SuperFX boards that report no RAM
    (fixes Starfox)
  - bsnes, higan: added automatic dependency generation [Talarubi]
  - hiro/GTK: appending actions to menus restores enabled() state
  - higan: use board node inside manifest.bml if it exists
  - bsnes: added blur emulation and color emulation options to view menu
  - ruby: upgraded input.sdl to SDL 2.0 (though it makes no functional
    difference sadly)
  - ruby: removed video.sdl (due to deprecating SDL 1.2)
  - nall, ruby: improvements to HID class (generic vendor and product
    IDs)

Errata:

  - bsnes, higan: on Windows, Application::Windows::onScreenSaver needs
    `[&]` lambda capture, not `[]`
      - find it in presentation/presentation.cpp
