Initial logical volumes (LVM) As well as encryption support.

- Support for logical volumes so we can get access to a larger /system
partition by taking space from /data (mmcblk0p2) /system initial size is
600MB and can get easily upgradable by tweaking the updater.sh

- Adding support as well for encryption. Depending when data/data is encrypted
or not, the contents of it goes either on data/data or on the /datadata
partition.

- Updated the updater.sh from aries to take care of the LVM handling.

Initially made for Aries devices, adapted over for YP-G1.
