[Languages] Ruby is coming along on .NET

I have been checking out a couple of newer implementations of Ruby for .NET.  Each offers something different and it is obvious that we are getting closer to having a really usable variant of Ruby on .NET in the near future.  Here are my current favorite contenders:

• Ruby.NET, by Gardens Point
• RubyCLR Drop 4, by John Lam
• IronRuby, by Wilco Bauwer

Each of these implementations has features worthy of notice and emulation.  Congratulations to the people behind them for contributing such fine work!
