- fixed use of IFS in probeNetworkCard and loadNetworkCard
- try to load hwinfo detected network modules in loadNetworkCard
  but don't fail if there are none detected or the load failed.
  udev normally loads the modules correctly
- ask interfaces for their MAC and IFace name directly instead
  of using hwinfo, that's faster and more reliable
- fixed updateOtherDeviceFstab to add devices by disk ID
