Restructuring was equivalent to:
  mv COPYING.txt LICENSE.txt
  mkdir jmdictdb
  mkdir bin
  mv python/tests .
  mv python/lib/* python/lib/.htaccess ./jmdictdb
  rmdir python/lib  # now empty
  mv python/* ./bin
  rmdir python  # now empty
  mv pg db
  mv patches db/updates

Added setup.py and README.md
