* Commit for 2.1.0.

* Added Dutch translation from Lieven Bridts, with tweaks from
  Guus Houtzager.

  from Pete Wenzel.

* Added non-zero exit code to BackupPC_zcat when uncompress fails.
  Patch from Pete Wenzel.

* Cosmetic changes to PC Summary and Log file language strings from
  Pete Wenzel.

* BackupPC::Lib tries to be more careful when renaming the backups
  file to backups.old.  There have been reports of backups being
  empty, perhaps when the BackupPC data file system fills up.
  Now backups is not renamed to backups.old if backups is empty.

* BackupPC now closes stderr and stdout before renaming and
  re-opening the log file.

* Pre/post backup/restore/archive commands now correctly set
  "type" to either incr/full/restore/archive, and now cmdType
  is the type of Pre/post backup/restore/archive command.

* BackupPC_archive correctly terminates archive processes on
  alarm or cancel.

* Updates to BackupPC_stnd.css with absolute font sizes instead
  of relative.

* BackupPC_dump now makes sure that the $Conf{FullAgeMax} check
  also ensures the full backup is older than the maximum age
  expected from $Conf{FullPeriod}.
