Update to bsnes v019r23 release.

Ok, this is a very important WIP release. Note that
this file is rather large, please mirror it if you must link to it
elsewhere.

               Included are two executables:
               bsnes_adsp.exe - This version uses anomie's S-DSP
emulator, clocked at 32khz
               bsnes_bdsp.exe - This version uses blargg's S-DSP
emulator, clocked at 1.024mhz

 Please note that blargg's code is experimental and in-progress. That
said, I have been unable to find any errors with it so far. I hope I
haven't missed anything blargg wanted me to do before release.
Everyone, please give your thanks to blargg for creating this emulator
and allowing me to use his code :)

 This day marks an important milestone, at least in bsnes, possibly in
the SNES emulation scene: the addition of a subsample-accurate S-DSP
emulator brings us one major step closer to the most faithful SNES
emulation that will ever be possible. Excepting bugs, this now gives
us bus-accurate S-CPU, S-SMP and S-DSP cores. It is not possible (nor
desirable) in software to get more precise than bus-level accesses.
The only core component remaining using an older, less faithful
approach is the S-PPU[1/2], and is not so coincidentally the source of
the only remaining bugs in bsnes. This will very likely be the biggest
leap forward in accuracy that will ever be seen for S-DSP emulation
from this date on.

 The old win32 interface is now completely broken, so I am forced to
distribute using lui. As such, I've fixed the NTSC/PAL mode switches,
and added software video filter selection to the UI. Any configuration
changes that are not in the menu will have to be done via the config
file for the time being. I have also added the log audio data option
back to the misc menu. If you are not able to get 60fps in bsnes, or
would like to analyze the audio output between adsp and bdsp in
another program, you can use this option. Also, I'm aware of the lui-
specific issues, such as audio repeating when entering menus. lui is
still a work in progress.

 Please test all of the games you can, and look for subtle audio
differences and the like. Bugs, improvements, whatever, would be very
useful to know. Please keep in mind that every commercial game ever
released was tested by both FitzRoy and tetsuo55, and there are
currently zero known problems with anomie's S-DSP emulator. Also note
that blargg's emulator will be slower, by nature of being more low-
level. I'll leave the decision on which core to enable by default to
you guys. Eventually, I'll have polymorphism fully functional, and
this will be a runtime-selectable option, and not require two separate
builds. But still, we unfortunately have to pick one to be the default
setting, which I hope does not offend anyone :(

 I'm very appreciative and in debt to both anomie and blargg for their
help with S-DSP emulation. They have both done a very large service to
us all by creating these cores, so I thank both of them again for all
their hard work, and for allowing me to use their work in bsnes.
