- added better information about disk Volumes
- fixed partids for LVM setup:
  * The value kiwi_RootPart must always be a number, whereas
    in case of LVM we also provide kiwi_RootPartVol which takes
    the name of the root volume
- fixed missing mount and fstab entry for allfree volume
  * the volume flagged with freespace="all" was ignored in the
    mount and fstab setup code
