fixes #530

a few issues with the solution

• needs a custom corpus for GB and German https://github.com/keredson/wordninja#custom-language-models
• needs support for non-Ascii characters Update wordninja.py keredson/wordninja#13
• ideally would return multiple alternatives return list of all options sorted by likelihood keredson/wordninja#23
  • now implemented -> return list of all options sorted by likelihood keredson/wordninja#23 (comment)
