Added notifications concerning `rawnand.bin` as to whether or not it is one file, where the combined files were combined, and letting the user know to continue with quickstart guide.
Updating the yuzu_copy.bat to create the `%appdata%/yuzu/sysdata` folder if it doesn't exist, and to update info about an error if the rawnand.bin is one complete file.
Tidied up a few errors. Updated yuzu_copy.bat, left the original script alone, but edited in away for the .bat to check if the backup has a nand ID or not.
