version 1.3.5

• added French translation, contributed by Raphaël Huck
• find more solutions; in response to bug #7
  • added an optional "slow search" mode that doesn't prune the search tree
    as aggressively as the standard search.
  • as a result of this, it runs significantly slower, but it finds a larger
    number of distinct, equally good solutions for some game positions.
  • it's activated by system property "UseSlowSearchMoreSolutions".
    (for example in file appstart.properties,
    or as VM parameter -DUseSlowSearchMoreSolutions)
  • this option is semi-hidden (not in GUI, but only in properties file) and
    set to "off" by default, because it slows down the solver significantly,
    so much that longer solutions can't be found at all.
