-had to remove wii drive light flashing during wait animation. even though i added NULL to nanosleep() it caused wiiflow lite to freeze right when the wait animation was to start. when i removed it everything works fine. besides the wii u doesn't have a disc slot light.
-note - strangely going from ppc r30 to r32 wiiflow lite boot.dol grew about 24k. also somehow ext_booter.bin is now marked as changed but i don't know what's different.
-only use the internal wii aes hardware if we do have hardware access (should fix dolphin-emu and neek2o)
-(hopefully) made the gc installer and the wait message display safer
-code cleanup, removed some unneeded stuff
-increased our usable mem2 by 1mb
