- fixed creation of EFI capable USB stick install images
  * the code which makes use of the bios_grub flag was not applied there
- make the partition based installation smarter (bnc #836780)
  * the current implementation shows a list of partitions to select
    if there is a choice. however this could be done better by
    taking the size, partid and fs-label information into account.
    With this patch the user only has to choose a partition if there
    is really more than one partition which matches the size and
    partid and filesystem label constraints
