- fixed creation of KIWICache object, was missing the xml pointer
- fixed cleanMount function to work if $root dir can't be
  created. It might happen that at that point kiwi already
  mounted some stuff which can be released via cleanMount
  but cleanMount returned if no $root location was created.
- added vmxFlavour-uefi and xenFlavour-uefi profiles to the
  suse-SLE11-JeOS template image description. Given that
  SLE11 SP3 is used these profiles can be used to build
  UEFI images based on grub2
- DB: update. wrote about the different union mount methods for pxe
- DB: rebuild documentation
- changed isofrom feature:
  + splitted information provided in isofrom into two parts
    isofrom_device= and isofrom_system= the two were set in
    common and seperated by a colon before. This caused
    trouble when the colon is part of the device information
  + added support for ISO from NFS (bnc #805771)
    isofrom_device=nfs:<ip>:<export-path>
- added network drivers and nfs stack to isoboot for
  openSUSE 12.3. This allows to boot live ISO's via pxe
  as explained in (bnc #805771)
