DeSmuME svn r2250

NDS模拟器DeSmuME svn r2250版，新版改进如下：

r2245
I finally figured out why 2D and 3D get desynced when skipping 3D frames.
Thus, I fixed the frameskip system so it'll also skip 3D frames. 2D and 3D stay synchronized, and frameskip is now much faster when using the soft rasterizer, for example.
r2246
Win32 - disabled savestate, loadstate, and setsaveslot hotkeys when no rom is loaded.
r2247
win32: add wx stub. with this, we could launch a wx dialog from win32 driver. this is not an endorsement of wx or even the philosophy of cross platform ui but rather a favor to those lunatics that mumble about cross platform stuff, so that they can drop wx dialogs into the emu core and launch them from windows without having to rewrite the entire windows port to use wx.
r2248
Adapt to new frameskip api, there's something strange here, at frameskip 1 i have 30 more fps and the poor frameskip limiter does not kick in.
r2249
Adapt gtk-glade to new frameskip api, the behaviour looks a bit saner that the gtk one :|
r2250
Fix some things in the disassembler.
