Various doc tweaks

- "Optimized baseline entropy coding" = "Huffman table optimization"

  "Optimized baseline entropy coding" was meant to emphasize that the
  feature is only useful when generating baseline (single-scan lossy
  8-bit-per-sample Huffman-coded) JPEG images, because it is
  automatically enabled when generating Huffman-coded progressive
  (multi-scan), 12-bit-per-sample, and lossless JPEG images.  However,
  Huffman table optimization isn't actually an integral part of those
  non-baseline modes.  You can forego Huffman table optimization with
  12-bit data precision if you supply your own Huffman tables.  The spec
  doesn't require it with progressive or lossless mode, either, although
  our implementation does.  Furthermore, "baseline" describes more than
  just the type of entropy coding used.  It was incorrect to say that
  optimized "baseline" entropy coding is automatically enabled for
  Huffman-coded progressive, 12-bit-per-sample, and lossless JPEG
  images, since those are clearly not baseline images.

- "Progressive entropy coding" = "Progressive JPEG"

  "Progressive" describes more than just the type of entropy coding
  used.  (In fact, both Huffman-coded and arithmetic-coded images can be
  progressive.)

- Mention that TJPARAM_OPTIMIZE/TJ.PARAM_OPTIMIZE can be used with
  lossless transformation as well.
