- fixed use of swapsize in oem size settings
  + the boot code adds the swap size as additional needed space
    to the oem-systemsize value thus it's wrong to test if swap
    fits into oem-systemsize. Robert had that before so this was
    correct, sorry Rob for changing this
- DB: update documentation
- DB: rebuild documentation
- added 'which' package to boot image descriptions for
  openSUSE 13.1. which was formerly provided by util-linux
  and is now an own package (bnc #816709)
