super processing: use logical flag to denote super status

Browse Source 
To support all partitions that are on the super partition
we now parse for the logical flag in fstab to denote super
status.

- Remove guards for the first character being '/'.
- Skip commented lines in fstab
- Build Backup_Display_Name from partitions in super.
The first four lines that are in fstab will be
displayed.
