Update to v104r12 release.

byuu says:

Changelog:

  - higan: URLs updated to HTTPS
  - sfc/ppu/background: use hires/interlace/mosaic-adjusted X/Y
    coordinates for offset-per-tile mode
  - sfc/ppu/background: hires mosaic seems to advance pixel counter on
    subscreen pixels
  - tomoko: added “Help→Credits” menu option (currently the page does
    not exist; should before v105)
  - tomoko: reduced volume slider from {0% - 500%} to {0% - 200%}.
    Distortion is too intense above 200%.
      - technically, I've encountered distortion at 200% as well in
        Prince of Persia for the SNES
  - nall/run/invoke: use program path for working directory
      - allows you to choose “Library→Import ROMs” from a different
        directory on the command-line

I don't know how to assign credit for the mosaic stuff. It's been a
work-in-progress with me, Cydrak, and hex_usr.

The current design should be correct, but very unpleasant. The code
desperately needs to be refactored, but my recent attempt at doing so
ended in spectacular failure.
