[gparted] Add PartitionLUKS class and create objects (#760080)

[Curtis Gedak <gedakc src gnome org>]

commit 99ff0c762835a0d501abcb9c0bb9d128c1607330
Author: Mike Fleetwood <mike fleetwood googlemail com>
Date:   Wed Nov 11 21:12:39 2015 +0000

    Add PartitionLUKS class and create objects (#760080)
    
    Absolute minimum implementation of a PartitionLUKS class which can be
    constructed, polymorphically copied and destroyed.  Contains an
    "encrypted" member of type Partition to represent the encrypted file
    system within the LUKS format.
    
    Create PartitionLUKS objects instead of base Partition objects when a
    LUKS formatted partition is found.  Only the base Partition object
    member values have been populated, and the "encrypted" member remains
    blank at this point.
    
    Bug 760080 - Implement read-only LUKS support
