Add other languages

[janpieterz]

I'd love to add libraries to this for c# and Javascript and follow one data structure setup, instead of cloning, releasing and having to keep the fork up to data with data structure additions/changes.

Would you be open for changing the repository structure? We could keep one data source, one license, but everything ruby specific (or C#, Javascript) would go one level down.

Rough structure draft:

• data
• implementations
  • ruby
    • bin
    • lib
    • spec
    • README.md
    • .rspec (and other files)
  • c#
  • javascript
• .gitignore
• LICENSE.txt
• README.md
• CHANGELOG.md
