MAJOR refactor. The volume is now abstracted into a model along with a partitionmap and partitions. Volumes and partitions are now controlled via an FSM to ensure that commands are called in the proper sequence. GRUB can now be installed properly onto loop devices by using dmsetup to fake a proper harddisk.
