Update to v104r01 release.

byuu says:

Changelog:

  - gba/cpu: synchronize to the PPU, not oneself, when the CPU is
    stopped
      - this bug was patched in the official v104 release; but not in
        the .tar.xz archive
  - ms/vdp: backdrop color is on the second 16-entry palette, not the
    first [hex\_usr]
  - ms/vdp: fix background color 0 priority; fixes Alex Kidd in High
    Tech World text boxes [hex\_usr]
  - tomoko: choose first option when loading files via the command-line
    [hex\_usr]
  - icarus: lo/hi RAM addressing was backwards; M68K is big endian;
    fixes save files in Sonic 3

Many thanks to hex\_usr for the Master System / Game Gear VDP fix.
That's a tricky system to get good technical information on. The fix
should be correct, but please report if you spot any regressions just in
case.
