Title: Add support for the Rubby programming language.

[Rubby](https://github.com/jamesotron/Rubby) is a toy language built on-top
of Ruby, and shares a lot of it's syntax. It seems to me that the existing
Ruby lexers get us so close to what we want that it's not really worth the
effort of writing one.
