Update to v106r48 release.

byuu says:

The problems with the Windows and Qt4 ports have all been resolved,
although there's a fairly gross hack on a few Qt widgets to not destruct
once Application::quit() is called to avoid a double free crash (I'm
unsure where Qt is destructing the widgets internally.) The Cocoa port
compiles again at least, though it's bound to have endless problems. I
improved the Label painting in the GTK ports, which fixes the background
color on labels inside TabFrame widgets.

I've optimized the Makefile system even further.

I added a "redo state" command to bsnes, which is created whenever you
load the undo state. There are also hotkeys for both now, although I
don't think they're really something you want to map hotkeys to.

I moved the nall::Locale object inside hiro::Application, so that it can
be used to translate the BrowserDialog and MessageDialog window strings.

I improved the Super Game Boy emulation of `MLT_REQ`, fixing Pokemon
Yellow's custom border and probably more stuff.

Lots of other small fixes and improvements. Things are finally stable
once again after the harrowing layout redesign catastrophe.

Errata:

  - ICD::joypID should be set to 3 on reset(). joypWrite() may as well
    take uint1 instead of bool.
  - hiro/Qt: remove pWindow::setMaximumSize() comment; found a
    workaround for it
  - nall/GNUmakefile: don't set object.path if it's already set (allow
    overrides before including the file)
