Update to v093r11 release.

byuu says:

Changelog:
- GBA: SOUND_CTL_H is readable, fixes sound effects in Mario&Luigi
  Superstar Saga [Cydrak] (note: game is still unplayable due to other
  bugs)
- phoenix/Windows: workaround for Win32 API ListView bug, fixes slot
  loading behavior
- ruby: added udev driver for Linux with rumble support, and added
  rumble support to existing RawInput driver for XInput and DirectInput
- ethos: added new "Rumble" mapping to GBA input assignment, use it to
  tell higan which controller to rumble (clear it to disable rumble)
- GBA: Game Boy Player rumble is now fully emulated
- core: added new normalized raw-color palette mode for Display
  Emulation shaders

The way rumble was added to ethos was somewhat hackish. The support
doesn't really exist in nall.

I need to redesign the entire input system, but that's not a change
I want to make so close to a release.
