Update to v105 release.

byuu says:

This release provides several major improvements to Mega Drive emulation
which enhances compatibility a good deal. It also includes important
Super Famicom mosaic emulation improvements, plus a much-needed SuperFX
save state issue fix.

Changelog (since v104):

  - higan: many improvements to Emulator::Interface to support
    forks/frontends
  - higan: refreshed program icon
  - icarus: new program icon
  - Game Boy Advance: slight emulation speedup over v104
  - Game Boy Advance: synchronize APU FIFO updates better
  - Mega Drive: added automatic region detection [hex_usr]
  - Mega Drive: support 8-bit SRAM
  - Game Boy Advance: fixed bug when changing to THUMB mode via MSR
    [MerryMage]
  - Master System: fix bug in backdrop color and background 0 priority
    [hex_usr]
  - Mega Drive: backgrounds always update output priority bit [Cydrak]
  - Mega Drive: emulated interlaced video output
  - Mega Drive: emulated shadow/highlight mode [Cydrak]
  - Super Famicom: auto joypad polling clears the shift register when
    starting
  - Super Famicom: added new low-entropy RAM initialization mode to more
    closely match hardware
  - Game Boy Advance: rumble will now time out after being left on for
    500ms
  - ruby: improved rumble support in udev input driver [ma_rysia]
  - M68K: `move.b (a7)[+/-]` adjust a7 by two
  - M68K: illegal/lineA/lineF opcodes do not modify the stack register
  - Mega Drive: emulate VIP status bit
  - uPD7725: improved emulation of OV1/S1 flags [byuu, AWJ, Lord
    Nightmare]
  - uPD7725: improved handling of DP, RP updates [Jonas Quinn]
  - Super Famicom: improved emulation of mosaic effects in hires,
    interlace, and offset-per-tile modes [byuu, Cydrak]
  - ruby: improved Direct3D exclusive mode monitor selection [Cydrak]
  - Super Famicom: fixed save state bug affecting SuperFX games
    [Cydrak]
  - Mega Drive: added workaround for Clang compiler bug; allowing this
    core to work on macOS [Cydrak, Sintendo]
  - higan: hotkeys now also trigger when the main window lacks focus yet
    higan is set to allow input on focus loss
  - higan: fixed an edge case where `int16_t` ↔ `double` audio
    conversion could possibly result in overflows
  - higan: fixed a crash on macOS when choosing quit from the
    application menu [ncbncb]

Changelog (since the previous WIP):

  - higan: restored `make console=true`
  - tomoko: if you allow input when main window focus is lost, hotkeys
    can now be triggered without focus as well
  - hiro/cocoa: fix crash on exit from menu [ncbncb]
  - ruby: smarter `double` → `int16_t` conversion to prevent
    underflow/overflow
