    installer: Add support for creating encrypted partitions.
    
    With the exception of /boot for the HAMMER install and / for the UFS
    install, allow the configuration of encryption of partitions via
    checkboxes in the partition creation stage.
Super nice, now we only need LVM support in the installer ;-)
