* Changes in '52', 08-Oct-2016:
  - UnZip.Streams: all procedures have an additional (optional)
      Ignore_Directory parameter.
  - Zip.Compress has the following new methods with improved compression:
      LZMA_3, Preselection_1 (replaces Preselection), Preselection_2.
      Preselection methods use now entry name extension and size for
      improving compression, while remaining 1-pass methods. 

For those interested about what's happening "under the hood",
LZMA.Encoding now computes an estimation of the predicted probabilities
of some alternative encodings and chooses the most probable one - it gives
an immediate better local compression. Sometimes the repetition of such a
repeated short-run improvement has a long-run positive effect, but
sometimes not - that's where it's beginning to be fun...

Enjoy!
