Removed some features that would see little use like the TWL mode option and the enable SD option. MBK init code moved and always used. Sets MBK to proper values for NTR mode (as documented in No$GBA). Since this build is now intended to be launched from a patched DSi System Menu, the touch screen mode change code has been removed and and this no longer requires a custom libnds build that isn't really available anywhere right now. :P
