-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)
currently loaded cIOS instead
-fixed bug of missing remount if no games are found with enabled
NAND emulation which made wiiflow hang
-added information for neek2o
-removed ios reload on boot when wiiflow is in neek2o mode
-made NAND file extraction MEM2 only
-fixed two not free'd memory allocations which could fill the
memory with unused stuff
-added debug SD information if found or not and if in __io_wiisd
mode (for dolphin-emu, neek, hermes ios)
-added automatically test if __io_wiisd mode works (no need to
overwrite things anymore to test that)
-added more intelligent IOS check (stub check, version check)
-removed unneeded cIOS information in neek mode
