Removed platform_boot_device_is_image() - platform_get_boot_device() now fills

in the adequate field in the kernel_args structure.
Renamed gCDFloppyBoot variable to gBootedFromImage (as network boot should look
similar).
The "kernel_args.boot_disk.cd" field is now maintained as well.
The print_item_at() menu function now prints the Menu::ChoiceText() instead
of that of its marked item.
