Update change log.
Bump VERSION, regen README.
v0.065_06

      Switched from using Archive::Tar to Archive::Extract.  The
      latter will attempt to use tar(1) to unpack the archive,
      which works much better with older archives.  This is a bit
      slower however.  If you don't have tar(1), it falls back
      to using Archive::Tar internally.

      NB: Archive::Tar also reads the entire archive into memory,
      so that probably explains why some of you have been getting
      out-of-memory errors.  The switch to Archive::Extract should
      help alleviate that problem (as long as you have tar).
