Title: Replaced RDiscount with RedCarpet and added syntax highlighting with pygmentize.

Removed the `rdiscount` gem with the `redcarpet` gem. This allows code blocks to be defined with the backticks (```), among other things.

Also, added syntax highlighted markup for code blocks. This is achieved by defining a new renderer for Redcarpet that takes the code blocks and "pygmentizes" them.

__Note__: To avoid issues on Heroku, the code is being syntax-highlighted using the [heroku-pygments service](http://pygmentize.herokuapp.com).
