By removing mutable state in VolumeWiiCrypted, this change makes partition-related code simpler. It also gets rid of other ugly things, like ISOProperties's "over 9000" loop that creates a list of partitions by trying possible combinations, and DiscScrubber's volume swapping that recreates the entire volume when it needs to change partition.
