Update to v094r41 release (open beta).

byuu says:

Changelog (since the last open beta):
- icarus is now included. icarus is used to import game files/archives
  into game paks (folders)
- SNES: mid-scanline BGMODE changes now emulated correctly (used only by
  atx2.smc Anthrox Demo)
- GBA: fixed a CPU bug that was causing dozens of games to have
  distorted audio
- GBA: fixed default FlashROM ID; should allow much higher compatibility
- GBA: now using Cydrak's new, much improved, GBA color emulation filter
  (still a work-in-progress)
- re-added command-line loading support for game paks (not for game
  files/archives, sorry!)
- Qt port now compiles and runs again (may be a little buggy;
  Windows/GTK+ ports preferred)
- SNES performance profile now compiles and runs again
- much more
