Sigh ...

asio.hpp needs #include <nall/windows/registry.hpp>

[Since the last WIP, byuu also posted the following message. -Ed.]

ruby drivers have all been updated (but not tested outside of BSD), and
I redesigned the settings window. The driver functionality all exists on
a new "Drivers" panel, the emulator/hack settings go to a
"Configuration" panel, and the video/audio panels lose driver settings.
As does the settings menu and its synchronize options.

I want to start pushing toward a v107 release. Critically, I will need
DirectSound and ALSA to support dynamic rate control. I'd also like to
eliminate the other system manifest.bml files. I need to update the
cheat code database format, and bundle at least a few quark shaders --
although I still need to default to Direct3D on Windows.

Turbo keys would be nice, if it's not too much effort. Aside from
netplay, it's the last significant feature I'm missing.

I think for v107, higan is going to be a bit rough around the edges
compared to bsnes. And I don't think it's practical to finish the bsnes
localization support.

I'm thinking we probably want another WIP to iron out any critical
issues, but this time there should be a feature freeze with the next
WIP.
