Add functions to read and write the AUPD (flash update) image. "--read-aupd aupd.bin" will read (and decrypt) the AUPD image, and "--write-aupd aupd.bin" will write (and encrypt) an image. Also fix a bug in the "diskmove" function which corrupted the AUPD image when a bootloader was installed. So in order to manipulate the aupd image, you need to restore a clean firmware partition, and install the bootloader with this version of ipodpatcher. Decryption functions based on the description and sample code at http://ipodlinux.org/Flash_Decryption
