Genera's disks on the runtime's USB driver

Genera now boots with its disks on the runtime's own USB driver: the runtime reads its few files from the boot partition into memory, takes the USB controller from the firmware, and serves Genera's world, FEP and log partitions itself. Genera does not notice the difference; the screenshot below came through that path.
