* Added some performance improvements to BackupPC::Xfer::RsyncFileIO

* Added some performance improvements to BackupPC::Xfer::RsyncFileIO
  for the case of small files with cached checksums.

* Added optional support for IO::Dirent which allows inode information
  to be extracted from the dirent directory structure.  This allows
  BackupPC to order some directory operations by inode, which on
  some file systems (eg: ext3) can results in a 20-30% performance
  gain.  On other file systems there is no real improvement.  This
  optimization is turned on automatically if IO::Dirent is installed.

* Added sorting by column feature to host summary table in CGI
  interface.  Implemented by Jeremy Tietsort.

* Added FreeBSD init.d file provided by Gabriel Rossetti.

* Applied small patch from Sergey to lib/BackupPC/Xfer/Tar.pm that makes
  it ignore "socket ignored" error on incrementals.

* Applied small patch from Sergey to bin/BackupPC_archiveHost.

* Added RsyncdUserName to the config editor.  Reported by Vicent Roca Daniel.

* configure.pl clears $Conf{ParPath} if it doesn't point to a valid
  executable.

* Added freebsd-backuppc init.d script from Gabriel Rossetti.

* Added documentation for BackupPC_tarPCCopy, including use of -P option
  to tar suggested by Daniel Berteaud.

* Config editor now removes white space at start of exec path.
  Reported by Christoph Iwasjuta.

* CgiDateFormatMMDD == 2 gives a YYYY-MM-DD format for CGI dates,
  suggested by Imre.
