NAND Emulation:

- Fixed Nand Emulation from SD-card.
- Fixed "CheckSave" functions.
- Fixed feature to flash a save file from emulated NAND back to real NAND.
- Some minor code cleanups and bug fixes.

neek2o: (neek2o r93+ only)
- Fixed return to channel function for titles on emulated NAND
- Added an option in wiiflow.ini: launchwiiflow in "NEEK2O" domain
  If this option is set to "no" the "exit to" option in home menu 
  will launch neek2o SM instead of the "DWFA" channel.
- If the return to channel option is set.. neek2o will return to 
  that specific title if that title exists on the emulated nand, even
  if the title was launched from real NAND.
