-added new option, "force_cios_rev" (default 0 (=disabled)), if you
set it to for example "force_cios_rev=250", then wiiflow will
use IOS250 for the AUTO setting, for reload when using
"force_cios_load" and when switching to emu nand in IOS58 mode
-added more detailed debug prints and on screen information about
the currently loaded cIOS
-minor cleanup in nand get file and external booter
-added support for wiiflow internal boot method in neek2o,
so you can use cheats, debugger etc if you boot channels in neek2o
(doesnt work if you are in real nand and just select boot neek)
possible to always have full NAND access no matter which IOS is
loaded currently
-fixed the sometimes again flashing wait message on game boot
-added some proper ISFS init and deinit methods with debug prints
-WIP commit for wii game/channel booting, now uses a internal
extra dol file to boot wii games and channels, that should be a
better way to fix game and channel booting
