Add encryption section into the Information dialog (#760080) 

For LUKS formatted partitions add an encryption section into the
Information dialog and display the type of encryption, path, UUID and
status of the encryption.

The file system section continues to display appropriate file system
details, including the partition graphic with the file system specific
border colour and correct usage.  The details will either be of a plain
file system, an encrypted file system, or nothing when there is no open
dm-crypt mapping, leaving the encrypted file system inaccessible.
Should there be LUKS encryption directly within LUKS encryption then the
details of the inner encryption will be displayed in the file system
section.  However this configuration will not be further supported by
GParted.

Bug 760080 - Implement read-only LUKS support
